How do you change a fuel pump on a 1999 Cavalier?

As the Cavalier is the stable mate of the Sunfire, I think you will have to drop the

fuel tank to access the fuel pump. If you pick up a Haynes or Chilton manual, it will

have detailed instructions on how to proceed.

Bear in mind that there are serious safety issues involved here. Any time you are working

with the fuel system, you need to be very careful.
