Had problems car died and would not start no fuel pressure changed fuel pump they gave me a pfs400 said it was the one for this car when looked up in service manual it calls for a ph307 (pfs250) are these pumps interchangeable. Still having problems with the fuel gauge is all over the place and it stalled out again.

Hello,

I always recommend the factory pump when doing a fuel pump, the numbers you gave I don't recognize. What brand pump is it? I would also replace the fuel pump relay as well.

Please let us know

Best, Ken

The part numbers are motorcraft, will changing the relay have any effect on the gas gage?

It would just have effect on the stalling not the gas gauge. Only Ford would know if the pumps are interchangeable. You would need to call the parts department.
