How do you replace the fuel pump in your 1996 Chevy Caprice classic?

Drop the fuel tank of your caprice, take off the bolts and remove the fuel pump from the fuel tank. Upon putting in the new fuel pump, be sure not to abuse the level as they are fragile and prone to give you the wrong fuel reading on your gas gauge

If a die grinder is available and dropping the fuel tank seems daunting, read on, Otherwise just disregard the following.

If you're up to it, you could always go into your trunk, remove the carpet of said trunk and Very Carefully take a Die Grinder to the outside of the hump. Just below that hump is the fuel pump, doing this eliminates any need to drop the fuel tank for the fuel pump and makes it easily accessible. The problem with this is that if you cut any deeper than the metal of the trunk itself, you risk hitting the wires connecting to the fuel pump, so if this is attempted, be slow and sure you aren't going too deep with your cut.

Start at one of the top sides, yes a SIDE, do not completely remove the hump or the fuel pump will have no protection from things in the trunk like the spare tire; work your way around the bottom of the hump to make a sort of lid. This should allow you to lift up this part of the trunk to reveal the Fuel Pump, making it far easier to access and replace.
