can anyone help me? I just purchased a 99 County Coach Magna 40' with a 7.4 detroit in it. I am having a fuel filter issue, I think. I drive for two hours and it sputters and loses power. I shut it off for 30-40 minutes and it is ok. I looked in the notes form the previous owner and found the fuel filter number, but I cannot find where this filter is. I can find the fuel/water seperator, but can not find the other cannister filter. Dealership is closed til after holidays, but need to get back home. I have looked everywhere and all I can find is the oil filter and the coolant filter. Any advice would be great.

I doubt that you are having fuel filter problems if you can drive it for 2 hours before trouble begins

That sounds more like a fuel tank venting problem, or perhaps a failing fuel pump. A clogged filter would show up almost immediately.

An unvented tank develops a vacuum as fuel is used and it becomes progressively harder to suck fuel out of the tank.

A fuel pump can sometimes fail as it heats up from extended use. I suppose the fuel line could also get hot enough to vaporize diesel fuel after awhile too, but that's a pretty rare problem with a diesel cause it doesn't vaporize as easily as gasoline.
