FUEL SUPPLY - General Information/On-vehicle Service13B-2
GENERAL INFORMATION
DThe steel fuel tank is located under the floor of the rear seats to provide increased safety and increase
the amount of luggage compartment space.
DThe fuel tank has been equipped with a valve assembly which incorporates a fuel cut-off valve to
prevent fuel from leaking out in the event of a collision for adjusting the pressure inside the fuel
tank.
DThe fuel pump module contains a fuel pump, fuel filter, and fuel pressure regulator.
ON-VEHICLE SERVICE
FUEL PUMP AND GAUGE ASSEMBLY (FUEL
PUMP)
1. FUEL PUMP OPERATION CHECK
Refer to GROUP 13A - On-vehicle service
2. FUEL PUMP REPLACEMENT
(1) Remove the rear seat cushion assembly.
(Refer to GROUP 52A.)
(2) Remove the service hole cover.
(3) Disconnect the harness connector, high-pressure fuel
tube, suction hose and return hose.
(4) Unscrew the mounting nuts to remove the fuel pump
and gauge assembly.
(5) Replace the fuel pump. (Refer to P.13B-7.)
(6) Install the fuel pump and gauge assembly. Tighten
the mounting nuts to the specified torque.
Specified torque: 2.5± 0.5 N·m
(7) Connect the harness connector, high-pressure fuel
tube, suction hose, and return hose.
Caution
1) Snap the high-pressure fuel hose or suction
hose one-touch joint into place, then pull back
slightly on the hose to assure it is securely
fitted. However, the connection should have
a play of approx. 3 mm.
2) Insert the return hose for 20 - 30 mm for
connection.
(8) Install the service hole cover.
(9) Install the rear seat cushion assembly.

FUEL PUMP AND GAUGE ASSEMBLY, PIPE
AND GAUGE ASSEMBLY (FUEL GAUGE UNIT)
1. Remove the rear seat cushion assembly.
(Refer to GROUP 52A.)
2. Remove the service hole cover.
3. Disconnect the harness connector, high-pressure fuel
tube, suction hose, and return hose.
4. Unscrew the mounting nuts to remove the fuel pump
and gauge assembly or pipe and gauge assembly.
5. Fuel gauge unit check. (Refer to GROUP 54 -
Combination Meter.)
NOTE
If the inspection shows that the basic resistance and
the height of float are out of the standard value, replace
the gauge unit.
(Refer to P.13B-8.)
6. Install the fuel pump and gauge assembly or pipe and
gauge assembly. Tighten the mounting nuts to the
specified torque.
Specified torque: 2.5± 0.5 N·m
7. Connect the harness connector, high-pressure fuel tube,
suction hose, and return hose.
Caution
(1) Snap the high-pressure fuel hose or suction hose
one-touch joint into place, then pull back slightly
on the hose to assure it is securely fitted. However,
the connection should have a play of approx. 3
mm.
(2) Insert the return hose for 20 - 30 mm for
connection.
8. Install the rear seat cushion assembly.
