Removal Procedure
Tools Required
J 42219-B Fuel Tank
Sender Wrench
Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur
if an ignition source is present. Never drain or store gasoline or diesel
fuel in an open container, due to the possibility of fire or explosion. Have
a dry chemical (Class B) fire extinguisher nearby.
- Remove the fuel tank. Refer to
Fuel Tank and Evaporation Emission Canister Replacement
.
- Disconnect the electrical
connectors from the fuel tank pressure sensor (6) and the fuel tank connection
cover (2).
- Remove the fuel pressure (5) and return lines (1) from the tank
connection cover and discard the clamps.
- Remove the air reference hose (3) from the fuel tank pressure
sensor.
- Remove the fastener (4) securing the fuel tank pressure sensor
to the fuel tank connection cover and remove the fuel tank pressure sensor.
Important: Do Not remove the steel band around fuel sender lock nut. This steel
band does not require removal in order the loosen the fuel sender lock nut.
- Remove the spring loaded clamp around the fuel tank boot. Note the position
of the clamp. The clamp must be reinstalled in the same position.
- Carefully pull the boot from the outer fuel tank housing.
- Remove the fuel sender
locking nut from the fuel tank by using the J 42219-B
fuel tank sender wrench.
- Lift the fuel tank connection cover from the tank and position
aside.
- Remove the fuel pump electrical
connectors (2) .
- Remove the hose clamp (3) from the hose at the fuel pump and discard.
- Remove the hose from the fuel pump.
- Remove the fuel pump assembly
from the fuel tank by pushing the tabs (3) inward to release the assembly
and then lifting.
- Note the position of the
fuel inlet screen and remove the screen from the fuel pump and discard.
- Remove the locking ring by pushing the tabs (1) inward and simultaneously
pushing the locking ring out of the fuel pump housing.
- Remove the fuel pump from the pump housing.
Important: Note the position of the fuel sender seal prior to removal. An incorrectly
installed seal can cause fuel leaks or EVAP DTCs to set.
- Remove the fuel sender seal (lip) from the fuel tank opening. Carefully
slide the seal over the wiring and hoses, then pull the seal over the fuel
tank connection cover.
- Discard the seal.
Installation Procedure
- Install the fuel pump into the housing making sure the fuel pump
suction pipe is seated in the recess in the bottom of the housing.
- Install the locking ring
in the fuel pump housing and snap the locking tabs (1) into the housing (2).
- Install a new fuel inlet screen onto the fuel pump in the same
position as noted during removal.
- Install the fuel pump assembly into the tank and lock down the
tabs.
- Connect the fuel line
to the fuel pump using a new clamp (3).
- Connect the fuel pump electrical connectors (2).
Important: Always replace the fuel sender assembly lip seal when servicing the
fuel sender assembly.
- Install a new lip seal on the tank as follows:
7.1. | Carefully pull the seal over the fuel tank connection cover. |
7.2. | Slide the seal over the wires and hoses to the fuel tank opening. |
7.3. | Fit the groove in the side of the seal into the lip in the fuel
tank opening. |
- Install the fuel tank connection cover on the fuel tank opening.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Use the J 42219-B
fuel tank sender wrench in order to
install the locking nut.
Tighten
Tighten the locking nut to 50 N·m (37 lb ft).
Be sure that the lip seal provides a snug seal between the fuel sending
unit and the fuel tank.
- Attach the fuel tank boot to the outer fuel tank housing.
- Install the spring-loaded clamp around the boot in the same position
as it was removed.
- Install the fuel tank pressure
sensor and tighten the fastener (4) to 2 N·m (18 lb in).
- Connect the air reference hose (3) to the fuel tank pressure sensor.
- Connect the fuel pressure (5) and return lines (1) to the fuel
tank connection cover using new clamps.
- Connect the fuel tank pressure sensor (6) and fuel tank connection
cover electrical connectors (2).
- Install the fuel tank. Refer to
