Fuel Sender Assembly Replacement

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 tire or explosion. Have a dry chemical (Class B) fire extinguisher nearby.
^ Provide proper ventilation when working with fuel in enclosed areas where fuel vapors can collect. The lack of adequate ventilation may result in personal injury.
^ Always wear safety goggles when working with fuel in order to protect the eyes from fuel splash.

NOTE: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.

IMPORTANT:
^ Always replace the fuel sender O-rings when reinstalling the fuel sender assembly.
^ The modular fuel sender assembly will spring-up when the snap ring is removed.
^ When removing the modular fuel sender assembly from the fuel tank, the reservoir bucket on the fuel sender assembly is full of fuel. The modular fuel sender assembly must be tipped slightly during removal in order to avoid damage to the float. Place any remaining fuel into an approved container once the modular fuel sender assembly is removed from the fuel tank.
^ Always maintain cleanliness when servicing fuel system components.

1. Relieve the fuel system fuel pressure. Refer to Fuel Pressure Relief Procedure.
2. Disconnect the negative battery cable.
3. Remove the spare tire cover, the jack, and the spare tire.
4. Remove the rear compartment trim panel.
5. Remove the (7) nuts retaining the fuel sender access panel.
6. Remove the fuel sender access panel.
7. Remove the fuel tank pressure sensor electrical connector.
8. Remove the fuel sender electrical connector.
9. Clean the fuel pipes, and fuel sender assembly to prevent possible fuel contamination during removal.
10. Remove the quick-connect fittings at the fuel sender assembly.




11. Remove the fuel sender retaining snap ring.
12. Remove the modular fuel sender assembly.
13. Clean the fuel sender assembly O-ring sealing surfaces.
14. Inspect the fuel sender assembly O-ring sealing surfaces.

INSTALLATION PROCEDURE





NOTE: Always re-attach the fuel lines and fuel filter with all original type fasteners and hardware.

Do not repair sections of fuel pipes.

IMPORTANT:
^ Care should be taken not to fold over or twist the fuel pump strainer when installing the fuel sender assembly, as this will restrict fuel flow. Also, assure that the fuel pump strainer does not block full travel of float arm.
^ Be sure that the fuel sender assembly retaining snap ring is fully seated within the tab slots on the fuel tank.
