High fuel pressure

[rick440]

I've got a 1980 Piper Warrior - with the 0-320-D3G lycoming engine. Intermittently, the fuel pressure has been acting unusual. On many flights, it's fine....steady at 5 psi. Other random times it will show pegged out at higher than 10 psi and then slowly return to 5 psi during the flight. Last night it started at 5 psi and then slowly rose to 9 psi which was 1 psi past the green range. On all the flights....the engine runs perfect.

I wanted to see if any other Piper owners have experienced this and then what the remedy was.

Appreciate the advise!
