Gentlemen, I have a 2001 Silverado Ex-Cab Sportside 4x4 w/ the 5.3L engine and it's time to change the fuel filter. As I don't have a service manuel yet, can anyone tell me where the filter is located.Thanks!

goto autozone.com they have a component locator feature as part of the website. Most likely it's on the frame under the cab but they can tell you for sure.

it's in the drivers side frame rail a little behind the drivers door. you need a 16mm and 13/16" or 21mm wrench to change it. it's recomended that you depressurise the fuel line by removing the fuel pump fuse while the engines running and allowing it to die. i usually don't bother with this only a little bit of fuel leaks out.

A bit of info for you. When hooking the lines back to the filter, be sure the o-rings are in place. One of mine slipped out and caused gas to leak.
