Fuel pumps are inside the gas tank so they are expensive to replace. The best prevention you can have for your fuel pump is to never let your fuel level get near empty. The worse thing you can do for your FP is to run out of gas. The gasoline in the tank cools the fuel pump and when it is empty, it is not cooled very well. Before I trained my wife to not let the tank get low, she ran out a couple times then in the same car, the fuels pump went out on the Jersey Turnpike, on a Sunday night late. Result, $700 and that was in a Chevy Caprice.
