1. Before servicing the fuel pump the fuel system pressure must be relieved.
2. Disconnect the negative battery cable.
3. Raise the car on a hoist.
4. Remove the fuel tank.
5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal.

NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.
WARNING: To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which components are being removed. This will reduce the possibility of the vehicle falling off the hoist.

Tools required: J 37088-A tool set, fuel line quick-connect fittings.


1. Relieve the fuel system pressure, refer to FUEL SYSTEM PRESSURE RELIEFSee: Fuel Pressure Release Service and Repair.
2. Drain the fuel tank, refer to FUEL TANK DRAINING.

See: Fuel Tank Draining Procedure3. Raise the vehicle on a hoist.

4. Remove the fuel filler hose from tank.
5. Grasp the fuel sender feed tube and in-line fuel filter quick-connect fitting. Twist the quick-connect fitting 1/4 turn in each direction to loosen any dirt within the quick-connect fitting. Repeat for other fitting.
6. Blow the dirt from the quick-connect fittings with compressed air.
7. Disconnect the quick-connect fittings:

o Squeeze the plastic tabs of the male end connector and pull the connection apart. Repeat for other fitting.

8. Disconnect vapor hose from connection (at front of tank).
9. Remove rubber exhaust pipe hangers to allow exhaust system to drop slightly.
10. Remove exhaust pipe heat shield bolts and heat shield.
11. With aid of an assistant, support tank, and remove front fuel tank strap attaching bolts and 2 retaining fuel tank straps.

CAUTION: DO NOT bend the fuel tank retaining straps, as this may damage the straps.

13. Remove vapor hose from fuel sender assembly.
14. Remove Vapor hose from vapor pipe (at rear of fuel tank).
15. Remove fuel tank from vehicle.

NOTE: If it is necessary to remove rust or burrs from the fuel level meter tubes: use emery cloth in a radial motion with the tube end to prevent damage to the O-ring surface.

* Using a clean shop towel, wipe off the male tube ends.
* Inspect all tube ends for dirt and burrs. Clean or replace components/assemblies as required.
* Inspect fuel line O-rings for cuts, nicks, swelling or distortion. Replace if necessary.
CAUTION: Never drain or store fuel in an open container due to the possibility of fire or explosion.

NOTICE: Do not attempt to drain fuel through filler neck, as damage to the filler neck check-ball may occur.

1. Disconnect negative battery cable.
2. Loosen fuel filler cap.
3. Raise vehicle.
4. Vent tube from restraints.
5. Clean fuel filler vent hose connection and surrounding area before disconnecting to avoid possible contamination of the fuel system.
6. Loosen fuel filter vent hose clamp.
7. Wrap a shop towel around fuel filler vent hose and slowly remove fuel filler vent hose from fuel tank vent tube.
8. Use a hand operated fuel pump device to drain fuel through the vent tube.
