Hi guys

I have a problem with my fuel pressure. I have an aeromotive fpr and a walbro 255 fuel pump. I can't turn down my fuel pressure below 3 bar. Anyone got any ideas? I've already replaced the fpr once.

well 3 bars is about where most fuel injectors are designed to operates at and if you need it to be less than that (43.5lbs) then verify if that regulator is designed for lower pressure which maybe dual use for injectors or carbs. If it should work with lower pressure then check your fuel return line as the excess pressure to has be diverted to the tank.
