I am sick and tired of having to be able to use the fast flow diesel pumps because of the older duramaxs small holes in the fuel caps...has anyone ever tried "bore" it open some more with a different cap or is there a part i can order to replace it with the newer style ones?

Most of the guys I know about that have cured this just replaced the Mouth with one of the newer ones.

mine as well go to a junk yard...damn thats expensive...do you know if its just the little mouth peice or is it all the way down to the tank?

I would try looking for a wreck in the junkyard first.

The one I replaced a few years back, had a soft tube in-between the nozzle on the tank and the mouth. It was not that hard to change. I had to change it because the lip on the mouth got rusty and I could not get a good seal with the cap.

Its just a mouthpiece. you keep your fuel hose thats on your truck.
