    Default Fuel In a Boost Guage

    Question: I have a mechanical Boost guage, autometer ultra lite marine pro comp. My boat no longer has a blower. Can i run a fuel line to the guage to montitor fuel pressure? It's the type of guage that measures vacuum and boost. Autometer does not make the guage i want anymore, which is a low psi mechanical fuel guage in that same face/trim. Rex Marine said autometer makes an electric fuel guage now, but i'd rather just run fuel to the boost guage if it will read properly. Thanks!

    You can do anything until it ruptures...

    This seems like a bad idea all around, I can't imagine the gauge itself would even be up to sealing gasoline since it is made to measure air pressure.

    I would run an isolator to it, so that way you dont have fuel running all the way up in case something happens. The gauge should work fine though.

    One of the guys at AutoMeter once told me that "pressure is pressure" and I could run air/fuel/oil, etc to any of their pressure gauges. The internals were the same. A lot of people don't like the idea of fuel pressure at the dash, and prefer the electric gauges. My STV has 60psi fuel pressure to the back of the 0-100psi mechanical gauge, at the dash.

    Default Autometer Has New MARINE Line

    Autometer has a complete new PRO COMP MARINE line of gauges, tachs, speedos

    Get a fuel psi gauge that is equipped to handle the purpose you want to use it for.

    I think that is his point, he doesn't want to get all new gauges because he needs just one...

    The isolator seems like just the ticket!
