How do you change a fuel pump on a 1996 Camaro 3.8 liter motor?

You have to remove the gasoline tanks, and you need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library. Assembly instructions will come with the new pump.

Recieved a cost estimate of 1,000 to replace fuel pump in 96 Camaro. In addtion to the fuel tank, dealer also said drive shaft and axel will have to be removed. 4/055/05

I too received an estimate for almost $1000, many years back and decided to do it myself. You basically have two options. First option is, you put the Camaro on a car lift, take the driver's side tire off. Take the Muffler off, heat shielding...etc... Remove the braces around the gas tank and lower the tank. Oh wait, did I forget to mention that it hits the axle and suspension on the way down and gets wedged in? Thanks Chevy, that makes sense... So all you have to do is pop off the rear drivers side shock, twist the neck of the tank sideways, bend the metal neck it a little and pull hard on that fuel tank to get it to come down. Disconnect 3 hose lines and 2 electrical connections and then there are 7 mini-bolts holding the actual pump in the tank. Swap pumps and reverse previous directions. This takes anywhere from 3.5 to 6.5 hours depending on your competency level.

Option 2 is to open the hatch/trunk up, lift up the carpet and pad....cut a giant hole or square (your choice) through the metal unibody about where you think the fuel pump (center of the tank) is, disconnect the hoses/electrical lines, unbolt the pump out of the tank and viola, you're half done is about 14 minutes. Swap pumps, swig a beer, and repair the massive hole you just cut through your unibody trunk metal. I recommend putting it on a hinge. Total time should be 1.5 hours and now you have an access door when your stupid fuel pump goes out again...
