    Anyone know what direction the fuel flows in this sensor? I don't see any indicator on it. Thanks.

    Doesn't matter. It's not measuring "flow".

    I hadn't considered that for some reason.

    I usually run mine on the return side also as the physical size of the passages make me concerned about it limiting flow.

    Mine is connected in parallel in the return line so no issues with it blocking flow. To save space I thought about just setting it in the gas tank but apparently it does need flow through the sensor.

    Nice bit of fab work right there.

    That does look good. I did the two y fittings with hard tubing.

    If I ever get around to putting a flex fuel sensor on mine, I will probably use this. Screenshot_2019-10-26-08-51-37.png #ad
