I have a 1994 Isuzu Rodeo and was wondering how easy it is to change the fuel pump. I went to Pep Boys and they are charging a grip! Is there a diagram or anything on the net that I can look at? Thanks for the help.

Replacing the fuel pump requires that you drop the gas tank. Whether you can do this yourself or not, depends on your experience and aptitude. You will also need a jack of some sort to ease the tank down.
