fueling problem
I have been having some issues with my 01 f350. On very light throttle it started surging slightly, feels like a gas engine running rich or flooding. When I give it a little bit more throttle it jumps and clears out. Then yesterday the fuel filter gasket blew out. I don't know if this is related or not, the filter was change about 3500 miles ago. Engine has 80,000 miles, and the outside temp has been in the 50's. Any ideas would be greatly appriciated. Thanks

How old is the engine oil (both time and miles)? What speed does the issue happen at, and what gear are you in when it does it? Sometimes these trucks will surge a bit at low speeds when the tranny has shifted into a higher gear and you're just barley pushing the throttle. You might just need to adjust your speed up or down a couple of MPH, or do an oil change if the IPR is acting funny.

Last oil change was 3500 miles and 3 months ago,(mobil 1 5w40syn) and I can feel it surge up to 35mph. It also happens when I have it manually in 1st, 2nd, and D. How do I check if I'm returning fuel?

Yes, Mobil1 5w-40 is diesel oil. Just EXPENSIVE diesel oil... 
I just got my $11/gal syn Rotella yesterday. When I went into WM to get my filter, they had some Mobil1 gasser oil (5w-30) for $22/5 qts. Why can't they sell 5w-40 for that?? Bastages. It's $28/gal.

Oh, and to check your return, open the fuel drain & have someone turn the key to "on" (have a catch container ready, and a short piece of hose attached to the end of the drain line helps a lot). You should have a slow steady stream, much like turning on a garden hose with no nozzle attached. If it comes shooting out of there like a nozzle is attached with it focused into a tight spray pattern, your return is likely blocked/kinked.
