My 22' Cummins is one of those that does not have a fuel filler cap. Now it does have a little plastic cap that just snaps on the filler tube but says "shipping use only" "remove". At first I thought I would leave that on there for just a little more protection from getting road grit down in the tank. But then I thought maybe it needs to be open for a vacuum or a vent for the tank. Probably just leave it off huh?
