When I switched my 442 over to EFI, I went through about a fuel filter a week, for about 6 weeks, until it finally cleaned itself up and stabilized. Why? In carburated form, even though there was a recirculatory function, the fuel only experienced filtration upon entering the "carbonator". Once switched over to EFI, the entire contents of the fuel tank gets recirculated through the system and filter at a substantial pace. I was cutting open the fuel filters everytime, finding just crazy amounts of muck in them! A very very fine particulate, cumulatively amounting to most likely 2 cups total before all was said and done! It would act just about exactly as you describe, responding perfectly if I'd shut it down and restart it, as it would backflush the plugged filter just enough to allow it to flow again (atleast until the backflushed muck got back into the filter again).


Could it be this simple?
