How to Replace a Fuel Pump in a 1987 Corvetteby Keith PerryUpdated November 07, 2017
Items you will need
Battery terminal wrench
Open end metric wrench
The fuel pump in a 1987 Chevrolet Corvette is a key component to engine performance. Fuel is supplied to the engine through an electric fuel-injection system. Inadequate fuel pressure in the fuel-injection system for the 350-cubic-inch, V-8 engine will result in stalling, stumbling or failure to run. A fuel pump failure will result in an engine that will not run at all. Fuel pump issues arise from internal components wearing out or damage from debris in the gasoline.
Fuel Pump Removal
Remove the negative cable from the battery using a battery terminal wrench. Remove the gas cap from the fuel filler leading into the gas tank.
Remove the fuel filler door by loosening the four Torx screws with a Torx bit and ratchet.
Peel up the rubber mat around the fuel tank filler tube. Remove the mat to expose the screws holding the fuel sender cover plate.
Remove the eight screws in the fuel sender cover plate with a small metric socket and ratchet.
Loosen the clamps for the fuel return line, fuel feed line and vapor hose with a flat-bladed screwdriver. Pull each hose gently to disconnect it from the fuel sender cover plate.
Disconnect the electrical connection to the fuel sender by gently prying the connector's locking mechanism with your hand. Pull the connector free from the sending cover by gently wiggling it with a lateral movement.
Vertically lift the fuel sender and fuel pump assembly out of the vehicle.
Remove both electrical connectors on the fuel pump. Loosen the nut on the fuel feed line with a open end metric wrench to remove the fuel pump.
Fuel Pump Replacement
Connect the new fuel pump to the fuel feed line by tightening the nut onto the fuel pump. Reattach both electrical connectors to the fuel pump.
Insert the fuel pump assembly into the gas tank and align the screw holes in the fuel sender cover with the openings in the fuel tank. Insert the eight screws into the fuel sender cover and tighten using a metric socket and ratchet.
Return the fuel feed line, fuel return line and fuel vapor hose to the original position and secure with the clamps. Tighten the clamps using a flat blade screwdriver. Slide the electrical connector over the receptacle on the fuel sender cover until it locks in place.
Return the rubber mat to its original position over the fuel sender cover.
Reinstall the fuel filler door and secure with the four Torx screws. Tighten the gas cap on the fuel filler tube.
Reattach the negative battery cable to the battery with the battery terminal wrench.
Gasoline is flammable and proper precautions taken to avoid fire or explosion. Always check for leaks after performing mechanical work on a fuel system.
