unit is combined with the fuel pump and sender assembly.

Fuel Filler Cap

General Description

Fuel filler cap includes vacuum valve.
In case any high vacuum happen in tank, the valve works
to adjust the pressure to prevent the tank from being
damaged.

Inspection

Check the seal ring in the filler cap for presence of any
abnormality and for seal condition.
Replace the filler cap, if abnormal.

CAUTION:
The fuel filler cap valve has characteristics.
A defective valve, no valve at all or a valve with the
wrong characteristics will do a lot of harm to engine
operating characteristics; be sure to use the same
fuel filler cap as installed in this vehicle.

Service Precaution

WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS), REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.

Battery

General Description

There are six battery fluid caps on top of the battery.
These are covered by a paper label.
The battery is completely sealed except for the six small
vent holes on the side. These vent holes permit the
escape of small amounts of gas generated by the battery.
This type of battery has the following advantages over
conventional batteries:

1. There is no need to add water during the entire

service life of the battery.

2. The battery protects itself against overcharging.

The battery will refuse to accept an extensive charge.
(A conventional battery will accept an excessive
charge, resulting in gassing and loss of battery fluid.)

3. The battery is much less vulnerable to self discharge

than a conventional type battery.

Diagnosis

1. Visual Inspection

Inspect the battery for obvious physical damage, such as
a cracked or broken case, which would permit electrolyte
loss.
Replace the battery if obvious physical damage is
discovered during inspection.
Check for any other physical damage and correct it as
necessary.

2. Hydrometer Check

There is a built–in hydrometer (Charge test indicator(1))
at the top of the battery. It is designed to be used during
diagnostic procedures.
Before trying to read the hydrometer, carefully clean the
upper battery surface.
If your work area is poorly lit, additional light may be
necessary to read the hydrometer.

a. BLUE RING OR DOT VISIBLE(5) – Go to Step 4. 
b. BLUE RING OR DOT NOT VISIBLE(4) – Go to Step

3.

3. Fluid Level Check

The fluid level should be between the upper level line(2)
and lower level line(3) on side of battery.

a. CORRECT FLUID LEVEL – Charge the battery.
b. BELOW LOWER LEVEL – Replace battery.

061RW001

4. Voltage Check

1. Put voltmeter test leads to battery terminals.

a. VOLTAGE IS 12.4V OR ABOVE – Go to Step 5. 
b. VOLTAGE IS UNDER 12.4V – Go to procedure (2)

below. 

2. Determine fast charge amperage from specification.

(See Main Data and Specifications in this section). 
Fast charge battery for 30 minutes at amperage rate
no higher than specified value.
Take voltage and amperage readings after charge.

a. VOLTAGE IS ABOVE 16V AT BELOW 1/3 OF

AMPERAGE RATE – Replace battery.

b. VOLTAGE IS ABOVE 16V AT ABOVE 1/3 OF

AMPERAGE  RATE – Drop charging voltage to
15V and charge for 10 – 15 hours. Then go to Step
5.

c. VOLTAGE IS BETWEEN 12V AND 16V –

Continue charging at the same rate for an
additional 3–1/2 hours. Then go to Step 5.

d. VOLTAGE BELOW 12V – Replace Battery.

5. Load Test

1. Connect a voltmeter and a battery load tester across

the battery terminals.

2. Apply 300 ampere load for 15 seconds to remove

surface charge from the battery. Remove load.

3. Wait 15 seconds to let battery recover. Then apply

specified load from specifications (See Main Data
and Specifications in this section).
Read voltage after 15 seconds, then remove load.
