4A•2 Fuel system - carburettor engines

General information and
precautions

General information

The fuel system consists of a fuel tank

mounted under the rear of the car, a
mechanical fuel pump, and a single or twin
downdraught carburettor.

On manual transmission and early automatic

transmission models, the fuel pump is
operated by an eccentric on the camshaft, and
is mounted on the rear of the cylinder head. On
automatic transmission models manufactured
from November 1986, an electric fuel pump
submerged in the fuel tank is fitted instead of
the previous mechanical type. The two relays
which supply the pump are located on the side
of the heater. One relay incorporates a safety
feature, in that its primary windings are
short-circuited to earth via the engine oil
pressure switch. When the engine is stationary,
this relay will not operate the fuel pump, but as
soon as the engine is running it will supply
current to the pump. The other relay operates
in conjunction with the starter motor to operate
the fuel pump for starting.

A number of different Solex and Weber

carburettors may be encountered and their
type and engine applications are shown in the
Specifications. All carburettors are of the fixed
jet downdraught type with either manual or
automatic choke arrangements. XY8 engine
models utilise a twin carburettor configuration.

The air cleaner contains a disposable paper

filter element, and on certain models
incorporates a flap valve air temperature
control system; this allows cold air from the
outside of the car, and warm air from the
exhaust manifold, to enter the air cleaner in
the correct proportions.

Precautions

Warning: Petrol is extremely
flammable - great care must be
taken when working on any part
of the fuel system. Do not smoke

or allow any naked flames or uncovered
light bulbs near the work area. Note that
gas powered domestic appliances with pilot
flames, such as heaters, boilers and tumble
dryers, also present a fire hazard - bear this
in mind if you are working in an area where
such appliances are present. Always keep a
suitable fire extinguisher close to the work
area and familiarise yourself with its
operation before starting work. Wear eye
protection when working on fuel systems
and wash off any fuel spilt on bare skin
immediately with soap and water. Note that
fuel vapour is just as dangerous as liquid
fuel; a vessel that has just been emptied of
liquid fuel will still contain vapour and can
be potentially explosive. Petrol is a highly
dangerous and volatile liquid, and the
precautions necessary when handling it
cannot be overstressed.

Many of the operations described in this

Chapter involve the disconnection of fuel
lines, which may cause an amount of fuel

spillage. Before commencing work, refer to
the above Warning and the information in
“Safety first” at the beginning of this
manual.

When working with fuel system

components, pay particular attention to
cleanliness - dirt entering the fuel system
may cause blockages which will lead to
poor running.

Throttle cable - removal and
refitting

Removal

1 The throttle cable is connected to a
spring-loaded reel which pivots on the face of
the cylinder head. On certain models, the reel
then operates the throttle lever on the
carburettor through a plastic balljointed
control rod.
2 Extract the spring clip from the adjustment
ferrule at the cable bracket on the cylinder
head. Release the cable end fitting from the
linkage.
3 Working inside the car, disconnect the
cable end fitting from the top of the

accelerator pedal arm.
4 Release the cable from the engine bracket.
5 Withdraw the throttle cable through the
bulkhead grommet.

Refitting

6 Refitting is a reversal of removal, but adjust
the cable at the ferrule to remove all but the
slightest amount of play. Check that full
throttle can be obtained with the accelerator
pedal fully depressed.

Choke cable - removal and
refitting

Removal

1 Remove the carburettor inlet cowl.
2 Unscrew the pinch bolts and disconnect
the inner and outer cables from the lever and
bracket (see illustration).
3 Release the cable from the clips in the
engine compartment.
4 Working inside the car, disconnect the
warning lamp wiring and detach the cable
from the support bracket.

Refitting

5 Refitting is a reversal of removal, but adjust
the cable at the carburettor end so that, when
the control knob is pushed fully in, the choke
valve plate is fully open.

Fuel pump - removal,
overhaul and refitting

Note: Observe the precautions in Section 1
before working on any component in the fuel
system.

Mechanical fuel pump

Removal

1 Disconnect the battery negative lead.
2 Where necessary for improved access,
remove the air cleaner assembly as described
in Section 2.
3 Disconnect the fuel hoses from the pump.
Plug the inlet hose.
4 Unscrew the pump mounting bolts and lift
the pump away (see illustrations).

13 If the valves are in good condition, locate
the diaphragm, push the operating arm into
position so that its forked end engages with
the groove in the end of the diaphragm rod,
with the coil springs in position.
14 Fit the pivot pin and stake around the
holes to secure both ends of the pin.
15 Fit the upper body so that the alignment
marks are opposite and then fit the screws
and tighten evenly.
16 Fit the filter screen and cover with gasket.

17 Refitting to the cylinder head is a reversal
of removal, but fit a new gasket.

Electric fuel pump

18 Refer to the procedures contained in Part
B, Section 5.

Fuel gauge sender unit -
removal and refitting

Note: Observe the precautions in Section 1
before working on any component in the fuel
system.

Removal

1 Disconnect the battery negative lead.
2 Raise the rear seat cushion.
3 Remove the circular plastic cover to expose
the sender unit (see illustrations).
4 Disconnect the electrical lead.
5 Using a suitable tool, unscrew the sender
unit mounting plate to release it from the
securing tabs.
6 Withdraw the sender unit, taking care not to
damage the float as it passes through the hole
in the tank.

Refitting

7 Refitting is a reversal of removal, but use a
new sealing ring if there is any doubt about
the condition of the original one.

Fuel tank - removal and
refitting

Note: Observe the precautions in Section 1
before working on any component in the fuel
system.

Removal

1 Before the tank can be removed, it must be
drained of as much fuel as possible. To avoid
the dangers and complications of fuel
handling and storage, it is advisable to carry
out this operation with the tank almost empty.
Any fuel remaining can be drained as follows.
2 Disconnect the battery negative lead.
3 Using a hand pump or syphon inserted
through the filler neck, remove any remaining
fuel from the bottom of the tank.
4 Chock the front wheels then jack up the
rear of the car and support it on axle stands
(see “Jacking and vehicle support”).
5 Either remove the complete exhaust system
or, on later models, release the support band
on the silencer, and lower the system using a
jack under the tailpipe.
6 Release the handbrake cables from their
fuel tank and other guide sleeves - there is no
need to disconnect the cables.
7 Unbolt and remove the heat shield.
8 Disconnect the wiring from the fuel gauge
sender unit.

9 Unscrew the mounting and safety strap
bolts and nuts, then lower the tank - at the
same time disconnecting the filler, breather
and supply hoses.
10 If the tank is contaminated with sediment
or water, remove the fuel gauge sender unit as
described previously and swill the tank out
with clean fuel. The tank is moulded from a
synthetic material and if damaged, it should
be renewed. However, in certain cases it may
be possible to have small leaks or minor
damage repaired. Seek the advice of a dealer
or suitable specialist concerning tank repair.

Refitting

11 Refitting is a reversal of removal.

Carburettor - removal and
refitting

Note: Observe the precautions in Section 1
before working on any component in the fuel
system.

Removal

1 Remove the air cleaner assembly, as
described in Section 2.
2 Unscrew the bolts or nuts and remove the
air inlet duct from the top of the carburettor(s).
3 Disconnect the throttle cable or ball-jointed
throttle control rod from the carburettor(s)
with reference to Section 3 (see illustration).
4 Disconnect the choke cable with reference
to Section 4.
5 Where fitted, remove the short hose which
runs between the oil filler cap and the
carburettor.
6 Disconnect the wiring connector from the
idle cut-off solenoid as applicable.
7 Slacken the retaining clip, and disconnect
the fuel feed hose from the carburettor. Place
wads of rag around the union to catch any
spilled fuel, and plug the hose as soon as it is
disconnected, to minimise fuel loss.
8 Make a note of the correct fitted positions
of all the relevant vacuum pipes and breather
hoses, to ensure that they are correctly
positioned on refitting, then release the
retaining clips (where fitted) and disconnect
them from the carburettor.
9 Disconnect and plug the carburettor
coolant hose(s). Plug the hoses immediately
to prevent coolant loss.
10 Unscrew the nuts and washers securing
the carburettor(s) to the inlet manifold.
Remove the carburettor assembly from the
car. Remove the insulating spacer and/or
gasket(s). Discard the gasket(s); new ones
must be used on refitting. Plug the inlet
manifold port with a wad of clean cloth, to
prevent the possible entry of foreign matter.

Refitting

11 Refitting is the reverse of the removal
procedure, noting the following points:

a) Ensure that the carburettor and inlet

manifold sealing faces are clean and flat.
Fit a new gasket, and securely tighten the
carburettor retaining nuts.

b) Use the notes made on dismantling to

ensure that all hoses are refitted to their
original positions and, where necessary,
are securely held by their retaining clips.

c) Where the original crimped-type Peugeot

hose clips were fitted, discard them; use
standard worm-drive hose clips when
refitting.

d) Refit and adjust the throttle cable and

choke cable (where applicable) as
described in Sections 3 and 4.

e) Refit the air cleaner assembly as

described in Section 2.

f) Top-up the cooling system as described

in “Weekly checks”.

g) On completion, check and, if necessary,

adjust the idle speed and mixture settings
as described in Chapter 1.

10 Carburettor - fault diagnosis,

overhaul and adjustments

Fault diagnosis

1 If a carburettor fault is suspected, always
check first that the ignition timing is correctly
set, that the spark plugs are in good condition
and correctly gapped, that the throttle and
choke cables are correctly adjusted, and that
the air cleaner filter element is clean; refer to
the relevant Sections of Chapter 1, Chapter 5
or this Chapter. If the engine is running very
roughly, first check the valve clearances as
described in Chapter 1, then check the
compression pressures as described in
Chapter 2.
2 If careful checking of all the above
produces no improvement, the carburettor
must be removed for cleaning and overhaul.
3 Prior to overhaul, check the availability of
component parts before starting work; note
that most sealing washers, screws and
gaskets are available in kits, as are some of
the major sub-assemblies. In most cases, it
will be sufficient to dismantle the carburettor
and to clean the jets and passages.

Overhaul

Note: Refer to the warning note in Section 1
before proceeding. The following procedures
are typical for the various carburettors
encountered on 205 models. Refer to the
accompanying illustrations for details of
specific carburettor types and component
locations.
4 Remove the carburettor from the car as
described in Section 9.
5 Unscrew the idle cut-off solenoid (where
fitted) from the carburettor body, and remove
it along with its plunger and spring. To test the
solenoid, connect a 12-volt battery to it
(positive terminal to the solenoid terminal,
negative terminal to the solenoid body), and
check that the plunger is retracted fully into
the body. Disconnect the battery, and check
that the plunger is pushed out by spring

pressure. If the valve does not perform as
expected, and cleaning does not improve the
situation, the solenoid valve must be renewed.
6 Remove the screws and lift off the
carburettor upper body.
7 Tap out the float pivot pin and remove the
float assembly, needle valve, and float
chamber gasket. Check that the needle valve
anti-vibration ball is free in the valve end, then
examine the needle valve tip and seat for wear
or damage. Examine the float assembly and
pivot pin for signs of wear and damage. The
float assembly must be renewed if it appears
to be leaking - shake the float to detect the
presence of fuel inside.
8 Unscrew the fuel inlet union and inspect the
fuel filter. Clean the filter housing of debris
and dirt, and renew the filter if it is blocked.
9 Undo the screws and remove the various
diaphragm covers and diaphragms. Remove
the diaphragm(s) and spring(s), noting which
way around all the parts are fitted. Examine
the diaphragm(s) for signs of damage and
deterioration, and renew if necessary.
10 Unscrew the jets from the upper body and
main body making notes as to their location
and arrangement.
11 Remove the idle mixture adjustment
screw tamperproof cap if fitted. Screw the
screw in until it seats lightly, counting the
exact number of turns required to do this,
then unscrew it. On refitting, screw the screw
in until it seats lightly, then back the screw off
by the number of turns noted on removal, to
return the screw to its original position.
12 Clean the jets, carburettor body
assemblies, float chamber and internal
drillings. An air line may be used to clear the
internal passages once the carburettor is fully
dismantled.
Caution: If high pressure air is directed into
drillings and passages where a diaphragm
is fitted, the diaphragm is likely to be
damaged.

13 Use a straight edge to check all
carburettor body assembly mating surfaces
for distortion.
14 On reassembly renew any worn
components and fit a complete set of new
gaskets and seals. A jet kit and a gasket and
seal kit are available from your Peugeot dealer.
15 Reassembly is a reversal of the
dismantling procedure. Ensure that all jets are
securely locked in position, but take great care
not to overtighten them. Ensure that all mating
surfaces are clean and dry, and that all body
sections are correctly assembled with their
fuel and air passages correctly aligned. Prior
to refitting the carburettor to the car, carry out
all the applicable adjustments, according to
carburettor type as described below.

21 To adjust the initial throttle valve opening,
fully unscrew the adjustment screw then,
using a piece of card as described in
paragraph 17, turn the screw until the valve is
opened by 7° 45’.

Fast idle setting

22 The fast idle setting is only made on the
left-hand carburettor with the reference
number 346. First close the choke valve then
check that the throttle valve has opened by
15º. If not, turn the adjustment screw as
required.

Choke opening after starting

23 To adjust the choke opening after starting,
first close the choke then pull the vacuum
opener rod and, using a suitable twist drill,
check that the gap between the bottom edge
of the throttle valve and the carburettor wall is
2.5 ± 0.3 mm. If not, turn the nut on the end of
the vacuum opener as required.

27 Close the choke flap, then fully operate
the pneumatic opener either manually or by
vacuum.
28 Using a twist drill, check that the gap
between the choke flap and barrel is 3.0 mm.
If not, turn the adjusting screw in the end of
the opener.

Throttle damper

29 Certain models may have a throttle
damper assembly, fitted to the carburettor on
a modified throttle cable support bracket, to
prevent engine stalling during gearchanges.

30 The assembly should not require any
adjustment, but if the throttle is held open by
the damper excessively during gearchanges,
adjustment can be made by loosening the
locknut, and altering the position of the
damper in the bracket as necessary. Tighten
the locknut on completion of adjustment.

Float level

34 Hold the cover vertical with the float arm
touching, but not depressing, the
spring-tensioned ball on the needle valve.
35 Using vernier calipers, measure the
dimension between the float and the fitted
gasket (see illustration). If it is not 9.0 mm,
bend the tongue on the arm as necessary.

Throttle normal idling position

36 This adjustment is made after overhauling
the carburettors, and is necessary to enable
the engine to be started and to prevent the
throttle valve sticking in the closed position.
The idle speed screw must be adjusted to set
the throttle valve 6° open, using a piece of
card as described in paragraph 17.

Fast idle setting

37 With the choke fully closed, the throttle
valve should be open by 14°. Adjust the fast
idle screw on the throttle lever to achieve the
desired setting (see illustration).

Choke opening after starting

43 To adjust the cold start device choke
opening after starting, Peugeot tool No 0.145G
is essential. The carburettor must be fitted and
the engine must be at normal operating
temperature and idling at the specified idle
speed (the cooling fan should have cut in and
out at least twice). The air cleaner hose and
the cold start device cover must be removed,
and the transmission selector lever should be
in the Park (P) position.

44 Fit the tool, then slacken the locknut and
turn the adjusting screw to bring the end of
the cam just into contact with the peg on the
tool (see illustration).
45 Using a 9.5 mm twist drill, check that the
choke flap has opened by 9.5 mm - if not,
adjust by means of the adjusting screw (see
illustration).
46 Disconnect and plug the diaphragm
vacuum hose, and using a 5.5 mm twist drill,

check that the choke flap has opened by 5.5
mm if not, loosen the clamp screw then hold
the roller against the top of the cam, and
adjust the lever until the drill will just pass (see
illustration). Tighten the screw and reconnect
the hose on completion.

Positive throttle opening

47 With the choke opening after starting
adjusted as described previously, press the
roller to open the choke flap and check that
the engine speed is 2000 rpm with the cooling
fan stopped. If necessary, adjust the screw to
obtain the specified speed (see illustration).
48 To adjust the choke cam, Peugeot tool No
0.145G must again be used. Fit the tool,
loosen the locknut, and adjust the screw until
the cam contacts peg (see illustration).
Tighten the locknut on completion.
49 With the adjustments completed, stop the
engine and refit the cold start device cover
