How to Relieve the Fuel Pressure on a 1993 Chevrolet Corvette


The 1993 Chevrolet Corvette uses a fuel pump inside the gas tank located at the rear of the car. Working on the fuel system should be performed only after relieving the fuel system pressure. This procedure is required to change the fuel filter or fuel injectors. The normal operating pressure for the fuel injection system is in excessive of 30 PSI. Failure to relieve the pressure before performing work could result in an injury or fire.

Tools Used: Tools, Needle-nose pliers

Relieve the Fuel Pressure

Open the fuse panel on the passenger side of the vehicle, located in the end of the dashboard. Identify the fuse location that is marked as “FP” on the back of the fuse panel door.

Remove the fuel pump fuse from the fuse block. Use a pair of needle-nose pliers if assistance in grasping the fuse is required. Insert the key into the ignition; start the vehicle, and let the engine run, until it stalls. Attempt to restart the engine several times, so as much of the fuel pressure has been relieved, as possible.

Tips & Warnings: Replace the fuel pump fuse in the fuse block when you wish to start the Corvette. Place the car in “Park,” or press the clutch in on an manual transmission before you attempt to start the vehicle. Make sure proper ventilation is in place, before running a car motor in an enclosed space.
