1988 Corvette TPI - How do you change fuel pump?

Answer 1

1988vette.com This procedure works if there is an adequate hole to remove the pump assembly. If not, see Chilton's manual. The removal hole will appear slightly larger than the plate... See below... Disconnect negative battery terminal. Locate ABC type fire extinguisher within easy reach. Do not smoke during any portion of fuel pump replacement. Sparks are bad too... Siphon as much gas out of the tank as you can(use an approved container for reuse) Remove the fuel fill door. (4 torx screws) Remove license plate for access to drain hose. Clean top of gas tank with water to remove any contaminants that could fall into the tank during this procedure. Do not allow any debris to fall into the tank! Remove gas cap. Place a clean non-shedding rag in the pipe. Remove rubber boot surrounding the gas fill pipe. The drain hose is located on the bottom of the boot. Pull it off. You can see it from the license plate opening. Carefully loosen the hoses on top. Remove hoses and plug each one with something clean. Remove the electrical connection from the car to the tank. Do not try to remove the connection that is attached to the plate. Remove the 10 bolts that secure the fill pipe plate to the tank. Avoid dropping any bolts when removing them. There is a rubber washer for each bolt but some will remain in the hole. Carefully remove and put on bolt. The pump, strainer, gas gauge float etc. are also connected to this plate. Carefully pry the plate free from the tank. Carefully pull the assembly out of the tank. The float will be on the left and can be pushed inward some for removal. It will be a tight fit. Note the orientation of the strainer. Set the whole unit on a clean towel. Remove the wire connection from the pump. Remove the strainer. Do not reuse strainer. The strainer is just pressed on and will take some force to remove. Slight force is necessary to remove the pump from the unit. Slide the interface between the pump and the metal fuel line up to allow it to be freed from the unit. (Reinstall in reverse.) Put the strainer on after the pump is attached to the bracket. Align the pump to the strainer and apply firm pressure to strainer and press into position. The fabric is torn easily so do not allow the metal insert to poke through. Make sure the strainer is in the same position as the one taken off. If not, it will not fit in the tank bottom or it will deform causing strainer failure. After the pump is back on the unit, slide the rubber/metal interface back down onto the pump. Attach the electrical fitting to pump. Make sure it is secured and locked. Replace in the tank. Remember to change the fuel filter before you pressurize (turn on the key) the system! It is located just under the passenger side door. Be careful not to strip the fittings. Fuel filter fittings must be aligned to the filter. This can be a bit difficult because of the deforming of the fuel line upon removal. If you jack your car up for this procedure block it to make sure it does not fall. That's bad. Good luck! After replacement, turn on and check for leaks
