1995 Dolphin with 460 motor

Thought we had a Vapor lock problem when it was real hot outside. The motor home motor would buck, miss, backfire, and just plane quit running. Let it sit for 1.5-3hrs and it would start up and run fine. We wound calling AAA 2 times to get towed off the main road, around the corner to cool down. Final results were a lean out of the injectors on the gas motor frying a piston.

A week later I was talking to a Ford Mechanic and he said it was not a vapor lock problem but a Fuel pump in dying stage. Had I knowen this it would have saved replacing the motor.

I should have check it out better before the real problem cost me big time.

  • Same thing happened on my 95 Pace arrow F-53 chassis. In tank fuel pump. At least you have a new engine so not a total waste.
  • On my 97 pace 460 it quit 25 mi from home on our first 1500 mi trip....had to be towed....replaced in tank pump with ford new and improved pump....drove it another 6000 mi and Iam having trouble again but don't think its the pump.have replaced pump/filter/regulator. I now have a complete horrible miss when it gets hot...have to disconnect the toad. I believe its the TFI Ign.modual which I just replaced,havent drove it yet. I'am on a trip....when I get home Iam going to install another pump,external,right before the filter.....Iam never paying another $750 for a pump in the tank.
    Iam tired of this F53 with only 50,000 mi. giving me trouble on every trip...thinking about a bumper pull and powerful truck.
