    LT1 Fuel pump

    I have a pretty good feeling my fuel pump is going out in my car.
    I havent really had a chance to look under there and look at things but if it is the fuel pump is it hard to change out with our cars?

    Well if your not doing the work yes it going to be hard. You can do it two ways, emtpy the fuel from the tank then drop the fuel tank to reach the fuel lines on top to remove the fuel pump from the tank. If you don't care to cut into your interior remove the rug from the hatch area. Then cut a door flap inside the hatch area of the car where the fuel tank sit's up and reach it from the top without dropping the tank.

    I'm not a fan of the floor cutting idea. I have changed a few for people.

    Easy if you have a lift. I remove the shocks and the panhard bar to drop the rearend as low as it will go for more room.
    A transmission jack comes in handy at this point and it doesn't require that you drain the tank this way.

    I do them in 3-4 hours with a couple of drink breaks in between

    It's really not as bad as some people make it out to be. If anyone should complain it should be me,,,since I generally work on old school stuff for a living where in tank pumps were unheard of and things are much easier for the most part.
