Was running this weekend and all was great. But noticed at end of the weekend my fuel pressure on one motor was pegged at 90! When I came off plane droped to 25 or so like the other.
Has me alittle concereced.

Some times the little filter under the regulator can get cloged up and give you hi [PSI] Or you might have a small kink in the return fuel line from the pump area, Or a blocked fuel line fitting some place, I have seen where a fitting was not driled out enough Or at all and that could show hi fuel pressure some times. Or the regulator is getting ready to go out.

hmmm

I'd double check the gauge with a test unit. Likely that the regulator is clogged up with some crap.
