Should I be worried? Is this a sign of a failing fuel pump? Lycoming has a max fuel pressure of 8 psi for carb engine. My EFIS alarm goes of at idle because fuel pressure briefly raises to 8.3 psi. This is without the electric pump on. Has anyone else had this issue. This has happened several time, it is only momentary and only happens at low rpms. Hmmmmm
