Have a '96 Georgie Boy Cruise Master on a Chevy 454 P30 chassis. DH thinks we are having a problem with the fuel pump. I did a search but most of the topics are not specific enough for him! Anyway if...
It might be the fuel pump but if it runs good on the road under load then I would look elsewhere first. Check the hoses for leaks/cracks that could let air in and fuel to drain back. Filters, but they would cause problems under load if bad. It is hard to do long distance problem solving. Bill
