How to Replace the Fuel Pump on a 1987 Chevrolet Corvette

The 1987 Chevrolet Corvette is the third year of the fourth-generation Corvettes. This model is equipped with a 350 cubic inch, fuel-injected engine. The fuel injectors require over thirty pounds per square inch (psi) to operate correctly. The fuel pump in the 1987 is located in the fuel tank and generates the required fuel pressure. Replacement of the fuel pump may be required when the pump fails. Pump failure is not a common failure but does occur in older or high mileage cars.

Tools Used: Battery terminal wrench, Phillips screwdriver, Flat blade screwdriver, Metric sockets, Ratchet with extensions

Replace the Fuel Pump

Remove the negative terminal from the battery using a battery terminal wrench.

Remove the four screws holding the fuel filler door to the brackets with the aid of a Phillips screwdriver. Remove the fuel filler cap by twisting it counter-clockwise.

Remove the rubber mat that surroundings the fuel filler pipe by peeling the mat up by hand. Disconnect the electrical connection to the fuel pump and fuel sender. Loosen the connections on the fuel return line, fuel feed line and vapor hose using a flat blade screwdriver. Disconnect the three lines from the fuel pump assembly.

Remove the six small bolts securing the fuel pump assembly to the fuel tank. Use a 10 mm socket, extension and ratchet to remove the bolts. Lift the fuel pump assembly up and out of the car.

Disconnect the electrical wire from the fuel pump. Remove the screws holding the fuel pump to the fuel pump assembly and separate the pump and assembly.

Attach the new fuel pump to the fuel pump assembly in the same position as the old pump. Tighten the screws holding the fuel pump to the fuel pump assembly. Attach the electrical connection to the new pump.

Insert the fuel pump assembly into the fuel tank and align the assembly to allow the assembly retention bolts to be inserted. Tighten the six bolts holding the assembly in place with the ratchet and extension.

Reattach the electrical connector, fuel feed line, fuel return line and vapor hose. Tighten the three lines using the flat blade screwdriver.

Replace the rubber mat over the fuel filler pipe. Install the fuel filler lid and tighten by rotating it in a clockwise direction.

Attach and tighten the fuel filler door to the brackets using the four Phillips screws. Replace the negative battery terminal on the battery and tighten using the battery terminal wrench.

Tips & Warnings

Place a towel over the rear of the car to protect the paint from scratches and dripped fuel.
