J 42219-B Fuel Tank
Sender Wrench
Removal Procedure
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 (FTP)
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 (1) 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 (1) from the fuel tank by using the J 42219-B
.
- Lift the fuel tank connection
cover from the tank and position aside.
- Remove the fuel level sensor electrical connector (1) from
the fuel tank connection cover.
- Unlock the fuel sensor by pressing the hook outward.
- Remove the fuel sensor by pulling upward on the hook to slide
the unit from the fuel 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 level sender in the tank by positioning the float
in first and sliding the unit into the slots in the side of the fuel reservoir.
- Push the unit down in the slot until the tab on the hook engages
in the reservoir.
- Connect the fuel level
sender electrical connector (1) to the fuel tank connection cover.
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:
4.1. | Carefully pull the seal over the fuel tank connection cover. |
4.2. | Slide the seal over the wires and hoses to the fuel tank opening. |
4.3. | 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
in order to install the fuel sender locking nut (1).
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 that the clamp was prior to removal.
- Install the fuel tank
pressure sensor and tighten the fastener 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 (2) electrical connectors.
- Install the fuel tank. Refer to
Fuel Tank and Evaporation Emission Canister Replacement
