Does anyone know where the fuel filter is located on a 2004 GMC 2500 HD with the 6.0 V-8? I've looked along the frame, but can't seem to find it.  

Sometime in 2004 they quietly switched to placing fuel filter in the tank where is was no longer easily end user serviceable. Slowly but surely they are making them less user friendly to doing your own repair work.  

Don't you hate how car companies are doing that these days? It really sucks when a fuel filter is a $200 dealer service only item. Bah.  

I kinda thought it could be in the gas tank. This isn't my truck though, it's my brother in-laws truck.  

They changed sometime in 2004 and all trucks made after that have it in the tank and models before that are external. Only Dmax's still have a external filter on newer ones.  

In the tank?  What's next, put a key on the engine compartment like BMW to prevent any type of maintenance!  Actually all the Duramax's have external fuel filter 01-07 LMM included, just changed mine on my LBZ & on brother's LB7.

Dmax has always had a external filter. I said newer ones because gas trucks did too until about 2004. Before that they all had them.  

Hello,
I have a GMC Sierra 1500 HD 4x4.
I lost the fuel pump last night. I purchased one today. Wow, approx. $300.0 for a plastic piece of crap.

Then there's the part of dropping the tank to replace the bad pump with the new pump. Working by myself, it will be a 2-day job.

All that GM had to do was put an inspection plate in the bed so the pump can be removed from the top. But no, they want you to take it to a dealer.

I friend of mine had to replace his pump twice in a period of about a year. More crap!

Well, I decided that I was going to only drop the tank one time. I have cut an inspection port in my bed.

I can remove the pump and get to all of the connections necessary for a pump change. The inspection port will be covered with a piece of aluminum diamond plate.

If you must drop the tank to change the filter on your truck, you might consider cutting you an inspection port. It will make pump and filter changing about a 20-minute job.

Good Luck,

Good luck with the swap.

If you haven't done it yet it's actually easier to remove the bed, or at least just slide it back. Just pull the bumper, the 4/6 bed bolts, and undo the fuel filler and slid the bed back a foot or so. Walla, access to the fuel pump.  

I tend to agree that removing bed is a easier way to go here. Also I want to stress that if you run tank low a lot it can shorten life of pump a lot as fuel cools and lubes pump. Basically you want to keep it above 1/4 for max life. Running it on fumes a lot is going to cost you a new pump sooner or later.  

yep, yep! ya don't even have to completely remove the bed, just unbolt it and rock it back straight up like a dump bed. i did my old '98 Dodge that way...twice.
