Hi Tom,

It's always an exciting adventure to "pick up" a coach!
I had the same issues when I picked up one of my coaches.
Personally I don't think I would put a boat tank in the cab, although It
would
probably work fine.
Ken is right the carb filter can stop up even with a filter ahead of it,
figuring that out had me going for a while!
It sounds like that may be what's happening to you, If I had it to do over,
I believe I would remove the carb filter,
get some extra hose and filters and install a filter in a convenient place
possibly behind the front bumper or grill.
When the filter needs to be changed find a SAFE PLACE to change it! I also
had pretty good luck just blowing backwards
through a filter to "clean" it.

Good Luck

While trying tpo go to sleep last night I was trying to come up with some
way to get home to FL
without haveing to drop the fuel tanks or crawling under the coach every 50
miles to change filters.
Not to mention the socks on the pickup tubes.

One of the PO's removed the mechanical fuel pump, probably when the electric
fuel pump was installed.
The electric fuel pump and the filter are mounted inside the frame rail
along with the filter.

What I thought was to put a 10~12 gal marine portable fuel tank on the floor
in front of the passenger seat
and take a fuel line from that through the floor. Re install a mechanical
fuel pump and plumb that to the
carb. I have a switch on the dash to turn off the electric pump so that is
not a problem. Also plug that line just incase.

The wife has to drive our Jeep anyway since this coach has 3.07 final and we
do not want the extra strain
on the coach until we get it FL and have it assesed at the COOP or at
Sirum's shop.

At least that way I can drive 100 miles or so between gas stations and not
have to crawl under the coach.

Any critique or suggestions are welcome. If this is a stupid idea tell me, I
have had plenty of them over the years.
