  • Pro flow #3503 loosing fuel pressure

    Small block chevy runs great until hot, loosing fuel pressure under acceleration, pressure dropping to 9 lbs. Any help or info would be appreciated Thanks

    Fuel pressure drops are most commonly due to plugged fuel filters or dying fuel pumps. If the filter is serviceable, service it. If not, replace it. If fresh filter doesn't fix it, I'd suspect the pump. Have there been any relevant changes made to the car recently?

      Thanks. No changes made recently. I am going for the pump, that's my guess. I appreciate the input/advice!
