How do you change fuel pump on 1996 Chevrolet lumina?

Answer 1

Obtain a shop manual, disconnect the negative battery cable, put the rear of the car safely in the air, WD or Kroil the fuel lines to ease removal, be certain the exhaust system is clear of the tank. Otherwise remove what exhaust components (generally only the intermediate pipe) are in the way of lowering the tank. Siphon fuel out of the tank to make it as light as possible. Disconnect the fuel lines, fill line & return lines, disconnect the electrical connector. Place a full floor jack with a 12"X12" board between the jack & the tank. Apply pressure. Unbolt the support straps from the body at the rear of the tank. Swing the straps clear. Check the perimeter of the tank making Shure it is clear of wiring, lines & anything that may prevent it from being lowered. Gently lower the jack, supporting the tank upright. Be careful NOT to bump the sending unit in any jarring way! It is sensitive & will not accurately give measure to your fuel gauge. I have had shops even mess this up. Now I have two cars with a quarter tank that are really empty! Needless to say I do my own work since you don't always get what you pay for. Sometimes in the automotive realm you just pay!

Slide the tank from under the car. Drain the rest of the fuel in a gas can. Using a brass (won't create sparks) chisel & hammer tap the notch on the pump assembly to slide the ring to unlock it. Remove the assembly, disconnect the pump from the connector. Place the new pump on the connector along with a new strainer. Check the condition of the tank. Remove rust with a brass wire brush. If you want to treat for rust now is a good time. Paint, POR 15 or rubber undercoating will help to seal moisture from the metal thereby halting rust. Reassemble the pump assembly into the tank. Put it all back together reversing above. Git 'er done :)
