Beacher,
As I stated in my original post we are looking for an alternative and really appreciated suggestions that were helpful toward that end, such as you provided in your last paragraph,and Angelo also suggested. Believe me we are on it!!!!
The main purpose for my post was to make other Axis/Vegas owners aware that there is a short non metal fuel line section where they could have a similar problem.
To be honest, I find your suggestion that we should inspect our vehicles if we have a rodent problem to border on offensive, and at the very least not very helpful! Any RV owner at any time could have a similar problem at a campground, in storage, or at home. We have had motor homes for the last 14 years, and they have always been parked at home on our motorhome driveway. In all those years we have never previously had a "rodent problem", inside or outside. However, we do an exhaustive pre trip check, and having smelled raw gasoline, we did not rest until we located the problem, and then were towed for absolute safety.
