I have a 1990 30' fleetwood southwind with a 460 ford and no fuel pressure, is there a fuel cut off, and where is it. Is there more than one fuel pump?

RVwantabe,

Your fuel pump is forward of the gas tank, under the motorhome.
Check the rubber fuel line from pump to tank. It may be cracked and all you get is air to the pump.You may have to drop the gas tank to change out the hose that has deteriorated with age. I would also check all the fuel lines to the engine.

Good RVing,
Steve

One other thing you could do before pulling the fuel tank down is check for 12V to the pump when the key is on. If power is there and lines and fuel filter are okay you will need to remove the fuel tank to access the in tank fuel pump. Unfortunately this is a common concern on the 1990 to 1997 F53 chassis. Don't skimp on the price to replace it. Cheap pumps burn out quickly and this is not a job you want to do more than once. Get a Ford replacement pump. The new ones have an updated turbine design that will last a long time.

Sorry about that, I missed the FORD denotation in the question.

The in tank pump is the only one for an EFI 460 f53 chassis. The fuel filter is mounted in the mid section of the left side frame rail.

Thanks for your help I'm going to trace the fuel line from the tank to the engine to assure that all filters and pumps are identified and replaced if needed.

My friend's went out last year. Had to be towed a ways so turned out to be pricey. Only one in the tank.
