How do you replace a fuel pump on a 2002 cadillac deville?

Answer 1

Open the trunk pull up the rug piece (after u remove the spare tire cover) and your gonna need a 1/4 inch socket 7mm its best fitted to a cordless drill or screwgun to speed up the process of removing the 10 or 12 bolts on the hatch cover you will see towards the right rear (looking down at the trunk furthest corner to the right) remove this cover and you will find the top of the fuel pump assembly module (fuel sender) start by disconnecting all plugs on the sender (and no contrary to popular belief you don't need to disconnect the battery before you do this BUT it is good safety to prevent your jackass buddy turning the key on to listen to the radio while the pump is plugged in with the fuel lines off BIG MESS IN YOUR TRUNK! ANYWAYS after removing the electrical connectors and assumming it hasn't been running (since your changing the pump) and there is no pressure in the tank (if there is simply open the hood take off the cover on top of the engine (plastic) by removing two 12 mm nuts on the top and simply pull up and towards you. then locate the fuel rail you will find a black plastic cap or a uncovered Schrader valve (which looks like the valve stem on your tire) take off the cap or if no cap take a pocket screwdriver or a pen and depress the pin in the center WATCH OUT FOR SPRAYING FUEL at 45 psi. After that's done remove the lines from the sender unit and turn the collar on the top securing it to the tank (there is a special tool for this but if you get creative you can get it off if its a metal locking ring you can hit it off with a screwdriver and hammer going around the ring ring slowly. then remove the sender unit (careful of the thin metal arm that's your fuel gauge level sensor) slightly tilt the sender when you almost have it out in order to help clear the level arm, CAREFUL FUEL WILL BE INSIDE THE SENDER UNIT DEPENDING ON HOW FULL YOUR TANK IS THE SEND COULD HOLD ABOUT A PINT OF FUEL IN ITSELF then reverse procedure to install have fun
