Fuel Level Sensor

FUEL INJECTION (FUEL SYSTEMS)

25.Fuel Level Sensor

A: REMOVAL

WARNING:
Place “NO OPEN FLAMES” signs near the
working area.

CAUTION:
• Be careful not to spill fuel.
• If the fuel gauge indicates that two thirds or
more of the fuel is remaining, be sure to drain
fuel before starting work to avoid the fuel to
spill.

NOTE:
The fuel level sensor is built in fuel pump assembly.
1) Remove the fuel pump assembly. <Ref. to
FU(H4SO)-55, REMOVAL, Fuel Pump.>
2) Disconnect the connector from fuel pump brack-
et.
3) Remove the fuel level sensor and fuel tempera-
ture sensor.

26.Fuel Sub Level Sensor

A: REMOVAL

WARNING:
Place “NO OPEN FLAMES” signs near the
working area.

CAUTION:
• Be careful not to spill fuel.
• If the fuel gauge indicates that two thirds or
more of the fuel is remaining, be sure to drain
fuel before starting work to avoid the fuel to
spill.
1) Release the fuel pressure. <Ref. to FU(H4SO)-
43, RELEASING OF FUEL PRESSURE, PROCE-
DURE, Fuel.>
2) Drain fuel. <Ref. to FU(H4SO)-43, DRAINING
FUEL (WITH SUBARU SELECT MONITOR),
PROCEDURE, Fuel.>
3) Disconnect the ground cable from battery.

4) Remove the rear seat.
5) Remove the service hole cover.

(1) Remove bolt (A).
(2) Push the grommet (B) down and remove the
service hole cover.

6) Disconnect the connector from the fuel sub level
sensor.

7) Disconnect the quick connector of fuel delivery
tube and jet pump tube. <Ref. to FU(H4SO)-65,
REMOVAL, Fuel Delivery and Evaporation Lines.>
8) Remove the nuts and bolts which install fuel sub
level sensor on fuel tank.

9) Remove the fuel sub level sensor.

B: INSTALLATION

Install in the reverse order of removal while being
careful of the following.
• Make sure the sealing portion is free from fuel or
foreign matter before installation.
• Align the protrusion (A) of gasket with the posi-
tion shown in the figure.
• Align protrusion (B) of the fuel sub level sensor to
the cut out in the fuel sublevel sensor upper plate.
• Tighten the nuts and bolts to the specified torque
in the order as shown in the figure.

NOTE:
Use a new gasket and retainer.

Tightening torque:

Fuel Filter

FUEL INJECTION (FUEL SYSTEMS)

27.Fuel Filter

A: REMOVAL

WARNING:
Place “NO OPEN FLAMES” signs near the
working area.

CAUTION:
• Be careful not to spill fuel.
• If the fuel gauge indicates that two thirds or
more of the fuel is remaining, be sure to drain
fuel before starting work to avoid the fuel to
spill.
• Be careful not to drop or apply any impact to
the fuel pump during work. This may deterio-
rate its performance.

NOTE:
The fuel filter is built in fuel pump assembly.
1) Remove the fuel pump assembly. <Ref. to
FU(H4SO)-55, REMOVAL, Fuel Pump.>
2) Remove the fuel level sensor and fuel tempera-
ture sensor. <Ref. to FU(H4SO)-57, REMOVAL,
Fuel Level Sensor.>
3) Disconnect the pump assembly connector from
the sub tank bracket assembly.

4) Cut off the tab holders connecting the sub tank
bracket assembly and the sub tank in four loca-
tions, and separate the two.

CAUTION:
Be careful not to damage the sub tank.

NOTE:
If the o-ring is remaining on the sub tank, remove.

5) Disconnect the fuel piping connector from the
fuel filter assembly in two locations.

6) Push to compress the fuel filter assembly in the
direction of the arrow, remove clip (A), and sepa-
rate the sub tank bracket assembly and the fuel fil-
ter assembly.

CAUTION:
When separating the sub tank bracket assem-
bly and the fuel filter assembly, be careful not
to damage the ground wire.

7) Disconnect the connector from the pump assem-
bly.
