On most trucks, the fuel filter is inside the fuel module (inside the fuel tank). It costs several hundred dollars to change it. I do not have any experience with seafoam and doubt it would do anything but make you feel better. What engine do you have and what modifications have you done so far? Many times the modifications cost you fuel mileage.

I have quite a bit of experience with Sea Foam, and love it. First I agree that your fuel filter is in the tank...nothing you can do there.
For the Sea Foam, do this:
1) Run 1/3 of a can very slowly through the brake booster, or slowly into the TB itself. Make sure the engine is running, and you pour it in slowly enough that the engine does not kill.
2) When you get the 1/3 can in there, stop pouring, and then shut off the engine. Again, make sure you stop pouring before you shut down the engine...you do not want to hydro lock it.
3) Let it sit 10-15 min.
4) Start the truck in a VERY well ventilated area. You will get clouds of smoke....that's normal. Run it a few minutes, then drive a couple miles to clear it out.
5) After the smoke clears out, shut it down. Remove and clean the throttle body with throttle body cleaner. It's also a good time to clean your MAF.

I bet you will get better performance after doing this. As far as what to do with the rest of the can of Seafoam? Put it in the gas tank!

I thought it was ok to run seafoam through your gas tank, if you planned on replacing the fuel filter shortly after ?

does fuel injector cleaners actually work, or am i wasting 5$ every 4 months lol ?

I've always used it, but I don't know if it helps, or simply "doesn't hurt". Piece of mind, I guess.

I like seafoam. I've used it off and on for a number of years. It makes me feel that I'm doing something positive for mileage and performance, but I honestly couldn't prove it. I've never run it strainght into the engine like EKINMN suggests, but mostly that's cause I don't want to be the first on my boock to find out what happens if I do it wrong. :)

Try to get the spray can of Sea foam, Sells at auto Bone. With the truck running. Spray a bit in the TB Unit. About 5-6 doses, then let the engine smooth it self out. Shut the truck down, Then Clean The TB Unit. I did that and the truck runs alot smoother.
