I've been thinking through the issues I had with a clogged filter on my most recent trip. 150 miles nursing the coach up the hills of the North Shore of Lake Superior gave me some time to think.

The PO of my coach did quite a few modifications when he had it. I am lucky that his workmanship was very good. One of the changes he made was to switch to electric fuel pumps. Each tank is rigged with its own fuel pump and an inline filter. The pumps are connected to run of the dash tank switch. When I was having my fuel supply issues last Thursday I reasoned that I could switch from the main tank to the auxiliary tank, thereby avoiding the inline filter on the main tank and continue on. That did not work. My problem wasn't resolved until I replaced the filter on the carb. Once that was replaced I was restored to full power. Over the weekend I also replaced the inline filters to be on the safe side and have a full set if filters in the spares kit in the coach.

So are my inline filters just acting as pre-filters? Should I run with just the inline filters and pull the carb filter? I'm okay with a "belt and suspenders" approach but am just wondering what others have done.

Thanks again!
