Hi everyone, I am pretty new to this forum, if anyone can give me the benefit of their experience it would be most appreciated. Recently acquired a 1970 4/4 with a ford engine and Mitsuba FP3 pump. The engine suddenly cuts out,after coasting to a stop can hear the pump working and the engine starts again. Over 20 mile journey cut out 3 times.Are these pumps repairable or best to change the whole unit. If so with what make?Thanks in anticipation.
