    Would it do any good to swap T splitter with Y shape for both supply and return along with replacing any hard 90 degree fitting to gradual elbows? May be sound stupid to the pros, just new to it and learn. Thnx.

    Suction just needs a T, return needs a splitter. You have an equalizing issue?

    yes. All was fine and week ago it started to give me a problem. Yesterday it was overflowing drivers side smaller tank and wont pick up any fuel from it. At night it stoped supplying fuel from both sides.

    Sounds like you just need to take a compressor to your vent lines and blow them out.

    I doubt you'll gain anything without a reprogram. Not like the old days of mechanicals.

    That is my doubt. Thats why am asking. I mean it is well known fact fluid doesnt bend so any time it hits 90’ elbow it stopes creates a back pressure before turning. But who am i to think big companies doing it for a reason. Just my thought it was.

    Not worth it for what you are doing. And the air dog? It might smooth out your idle but not much else
     
    deniss Thanks this.
