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:
Fuel pump assembly consists of fuel pump, fuel fil-
ter and fuel level sensor.
1) Release the fuel pressure. <Ref. to FU(H6DO)-
43, RELEASING OF FUEL PRESSURE, PROCE-
DURE, Fuel.>
2) Drain fuel. <Ref. to FU(H6DO)-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.

6) Disconnect the connector from fuel pump.

7) Disconnect the quick connector on the fuel deliv-
ery hose and jet pump hose. <Ref. to FU(H6DO)-

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.
• When assembling, point the protrusion of the
gasket (A) towards the front of the vehicle.
• Insert the protrusion (B) of the gasket into the up-
per plate. (3 places)
• Align the protrusion (C) of the fuel pump assem-
bly to the cut out in the upper plate.
• Tighten the nuts to the specified torque in the or-
der as shown in the figure.

NOTE:
Use new gasket and retainer.

Tightening torque:

4.4 N·m (0.4 kgf-m, 3.2 ft-lb)

C: INSPECTION

Connect the lead harness to the connector terminal
of fuel pump, and apply the battery power supply to
check whether the pump operates.

CAUTION:
• Wipe off fuel completely.
• Keep the battery as far apart from fuel pump
as possible.
• Be sure to perform the ON/OFF operation on
