    The Facet on my model 4 912 uls gravity flowed with no problems.

    I’ve got to figure out which kind of pump those are. I have one on hand that would act as a shut-off valve if not running.

    Here is a link to one that may suit your needs. I don't remember off hand which one I have in my Avid. JImChuk

    I’ve ordered a 40104 and a bunch of #5 hydraulic fittings. Thanks for that but Spruce was cheaper for the pump and got the ftgs too.

    Sorry for the later response. I think that's the pump I have, installed as JimChuck has done. You want low pressure so it can't overpower the float valves in the carbs.

    I installed the Facet pump before the fuel shut-off as there wasn’t enough room to easily shoehorn it after. Would have made replacement easier in the future but with only 12 gallons I can drain the system in a jiffy.

    The engine starts far easier! Nice benefit. (I have no primer)

    Gravity fuel flow virtually unchanged with the Facet pump too.
