    Not a truck guru (will be obvious after reading post)...

    Where can I find the fuel filter in my truck. I changed the transmission fluid and filter today but didn't get the time to do the fuel filter...got dark. I'm hoping someone will reply before tomorrow morning so I don't have to go crawling under my truck following the fuel line until I find it. Thx for your help.

    It should be on the inside of the left frame rail just under the drivers seat area. 8.1 liter trucks aren't that common but that is where the filter is on 6 liter trucks.

    04 6.0L are in the tank and are not servicable. Supoosed to last as long as the pump. This new system dosent recirculate the fuel like the old system. So I guess GM figured not nearly the amount of fuel will pass though it.

    Sorry, calhoun was correct. The fuel filter for your truck is in the tank. Pretty brilliant idea, I wonder where GM is finding thier engineers these days?

    Just replaced my first fuel filter on a gas GM product this fall. My 89 2500. It rusted in 2, ended up replacing my gas tank and fuel lines at the same time.

    Oh, by the way, there was no debris in the filter..... :p
