Before servicing the fuel pump the fuel system pressure must be relieved, see MAINTENANCE PROCEDURES/FUEL SYSTEM PRESSURE RELIEF.
Disconnect the negative battery cable.
Raise the car on a hoist.
Remove the fuel tank, see FUEL TANK AND FUEL LEVEL SENDING UNIT.
Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
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.
