NO START
Richard And Babs Ames:
Do you have http://racorfuelfilters.com/?gclid=CO-h-uCmwp8CFQzKsgod0RPJ0A this filter system? If so it is like the one we had on our 1997 Patriot. We developed a leak in the screen housing followed by a electric pump failure and leak. Ended up replacing with a http://www.maesco.com/products/racor/r_spn_intro/r_spn_intro.html filter with manual pump. Simple design and and less expensive replacement filters.

THANKS, - - PROBLEM SOLVED
AFTER ABOUT $500 THE CAT DEALER IN PORTLAND FOUND THE PROBLEM.
When I purchased the Marquis from Beaver Coach Sales in September 09, I had them do a $1200.00 service of all the major components.
New fuel filters, oil the works.
November 09 the coach wouldn't start:
The Cat Dealer Halton on the second visit found a DEFECTIVE GASKET ON THE NEW FUEL FILTER that was leaking air into the system.
They replaced the fuel filter and all is well.
What a nightmare for a NEW FUEL FILTER.
Rob Perry:
By the way, we got rid of the usless electric pump located by the fuel filters and had a CAT hand pump installed. It's a beauty.

You got off cheap. I have a $600 filter!
About two years ago I was driving south on I-5 and the engine started "lurching" like it was missing when climbing gentle hills. Each time it did, the ATC light flashed. Called Monaco and Cummins. (Yes, my Beaver has one of those!). Both were convinced I had a computer problem somewhere and an ATC signal was confusing the engine. I limped and lurched into the Cummins shop in Coburg, OR and left the coach for the weekend. Monday they went to work. After six hours of trouble shooting at $100 per hour with laptops and code readers, a seasoned mechanic suggested a fuel filter change "just to see what happens". That fixed the problem. It ran perfectly with the new filter.
It seems that the ATC light flashed because the engine de-rated for lack of fuel. Then it would "heal" as it got a little more fuel through the filter. Don't know why the filter plugged up. It had only about 2,000 miles on it.
