    LB7: SAC 45 overs, who is running them?

    I know it's been 5 years or so, but if you have the time, I'd love to see how you left this tune. Currently feeling my way through this exact same jungle at the moment.

    Air in the Fuel? Bad FPR? Bad FPRV? Video in thread.

    I had some time to play with it today. I slid some clear hose on the line from ficm to the filter head. Found bubbles coming through.
