just ran my car. read plugs. dead lean, stumbling. aeromotive a1000 pump and a4 regulator. my question is about fuel pressure. the guage at the carb is bouncing from 6-9psi when its running. I thought it should be more consistant than that. I have tried 9-15 psi at regulator at pump. Pressure it pretty consistant coming from pump. any help would be appreciated.
