2006 6.0L Stuttering Problem???
Hello Guys Girls just bought 06 f350 135,000 miles when the truck gets down to 1/4 tank of Fuel it starts to hold back @ around
60-65mph feels like it is running out of gas or cutting back on the gas pedal? if you stomp on it the truck will run fine but if you go back to the speeds listed above it does it again if i drive the truck in town at slower speeds it go's away? Like i said i just got the truck this is my second tank of fuel now and it did the same thing today any comments or thoughts of what this could be? Would be very much appreciated thank Tom.
P.S Do these trucks have a fuel restriction after it gets to a certain level?

No restriction for a low tank level.
Have you drained the HFCM (fuel water separator)? When was the last time you changed the fuel filter? You may have crud restricting the HFCM suction line. I assume you have the plastic fuel tank?
I would quickly install a fuel pressure gauge. If you do have a restriction or low fuel pressure, you can ruin injectors.

Hi Mark what kind of fuel pressure should i expect?
I will drain the fuel water separator tomorrow and change filters also do the 6.0L have two fuel filters?
Sorry I'm a newbie!

Yup - you have two filters and you should change them both. Tech folder has a few threads on the filter change.
Use only the motorcraft filters (or Racor who is the manufacturer of the motorcraft). You can also use filters from International. Do a search for part numbers if you need them (if they are not in the Tech Folder fuel filter change thread).
Fuel pressure must ALWAYS be above 45 psig. There is also a spec on how much pressure loss in the suction line is acceptable - I just don't recall what it is right now. I have seem lenzhotrod post it though.
