How do I make this short? We own a 1996 Holiday Rambler Endeavor with a B series Cummins. While having a PM performed the shop found a fuel leak emanating from the front half of the vehicle. A local shop said the fuel tank had to be dropped and couldn't handle it. We ended up traveling 50 plus miles to a diesel repair facility located off of the interstate. As it turns out, $700 later the tank was dropped and the fuel lines to the generator; which were dry rotting, were replaced. Here's the rub and somehow it's all connected. While jostling the tank, apparently all kinds of gunk was loosened in the process. Also, there was a loss of fuel pressure somewhere down the line. Things then failed in progression over a 4-6 week period. We lost the fuel solenoid shutoff valve and then the lift pump. Along the way we replaced three fuel filters, including the lift pump filter which failed on the trip to check everything out. The moral of the story is to regularly treat your tank with a good quality biocide and fuel treatment and to have pm's performed regularly. As older coaches become more affordable, more people are going to have these problems. If you buy one have a mechanic thoroughly inspect the coach; you'll be money ahead.
