I have a 1989 ford fleetwood flair 24N...bought it last year and its in great shape with 58k miles. Ran perfect all last year. Just got it out of storage last week. Ran perfect back to my house ( apprx 13 miles from storage place). Was letting it run some in my drive way while i was cleaning the exterior. It started sputtering and finally quit. Even the generator was acting up. Never did last year. Would have to hold in the button to keep the generator running. As soon as i let off the button the generator would quit. Hired a mobile rv mechanic to come out n service. He replaced the fuel filter, fuel pressure regualtor and even installed a new in tank fuel pump. Put the pressure gauge back on it after all of the work and the rv started with 35psi and would slowly lose pressure after a few minutes and finally quit around 8-10psi. ANY SUGGESTIONS OR OPINIONS I COULD IVE TO THE MECHANIC?

I'm more familiar with the Ford E-Series under Class C coaches. That said, the first couple years those units had fuel injection, it was Throttle Body (TBI) and they used two fuel pumps. One was in the tank and provided low pressure fuel to a high pressure pump located on the driver side frame rail. Did your mechanic check both pumps? The earlier in-tank electric pumps, used with carburetors, provided just a few pounds pressure. I don't know what the spec for the ones feeding the frame-mounted pump. Where was the filter he replaced? The on-frame unit I saw (1984 T-Bird TBI) had the pump and a filter on the same bracket. I don't remember if there was a second filter elsewhere.Your gas tank needs to be roughly 1/4 full to fuel the generator. That's all the farther down the pickup reaches. That's so you can't run yourself dry with the genset and not be able to motor out.

As silly as this may sound, trace the fuel line all the way from the tank to the engine. My old Holiday Rambler had a similar problem until we (the shop) found an in-line fuel filter that was added half way between the tank and the engine...making 3 filters in the system. Just and idea. Good Luck.

Also check for rotted rubber lines that may be cracked and letting air in. Especially problematic when using Ethanol fuels in vehicles not built for it. You may even want to replace all the rubber lines before they can leak and lead to other problems.

Thanks for the quick replies everyone. The fuel is roughly 4 months old. I took it out of storage just to drive it about 4 months ago and put about a half tank in it. As far as the fuel pump goes the mechanic replaced the in tank unit and a fuel filter located on the drivers side frame rail. I dont know of a 2nd fuel pump.

"ran perfect all last year and just got it out of Storage" (In Sept)

I'd drain all the fule, clean the tank and re-fill with fresh fuel

If it's diesel you may have an algae problem If it's gas the fuel has seperated.

Next time you store Diesel Seafoam additive Gas Seafoam for gas or Sta-Bil.

Read labels for how much.

Since both the engine and generator are acting up, I'd strongly suspect the fuel is bad because the generator has it's own separate fuel line into the gas tank and would not be affected by any fuel pump/fuel filters that are feeding the engine. At this point I'd also have a look at the spark plug for the generator.

Fuel tank vent, if air can't get in - fuel can't get out. Try it with the cap open.
