Condition/Concern:

The fuel filter location has changed. Service intervals and part numbers listed in some 2005 owners manuals are not correct. Later 2005 vehicle owners manuals have been corrected with this change.

Recommendation/Instructions:

For the 2005 model year, the fuel filter was changed from an external mount to internal version that is part of the fuel sender assembly. Due to the fuel filter location change, there is no longer a recommended fuel filter replacement criteria. Please disregard the fuel filter part number and the recommended service interval of 25,000 miles, listed in the 2005 mid-sized utilities owners manual.

Relist: I prefer a second opinion.

I guess you got two answers because you posted the question twice. The problem is not with us, it is with GM and the fact that they make mid year changes sometimes. Depending on when your truck was built both answers could be correct. I would suggest you check the location given, close to the front of the tank and if there is no filter there, then it is inside the tank and not normally service. GM does not specify when the change was made, only that it was. Sorry for the inconvenience, just trying to help you. But we are at the mercy of the manufacturers too.
