    Does anyone know of a decent 1.125”fuel pressure gauge with a smaller max pressure than 15#? If I’m going to run a max pressure of 5# I don’t need a gauge that reads 15# (I think 6-7# would be plenty).

    Pretty much most gauges read the higher levels. Only gauge I can remember was the very small Mallory gauges.

    WOWW! $88 for that gauge seems like a lot. Perhaps I'm still living in 1960.

    Wish ****s Hot Rod Carbs was still around. He had the best low pressure gauge around. I have one on my 39.

    The smaller the gauge the Less accurate.
    I have talked with quite a few engineers at name brand companies manufacturers..
    Look into Commercial, Aviation, Industrial there $$$ , $200 plus

    Marshall gauges on e-bay, there are quite a few variations of the 0-15 gauges in really small diameters.

    Marshal seems like good quality but can’t speak from years of use…

    I found this one online, it works great but is **** the hell ugly (IMHO). I removed it and plugged the hole, it is only needed for tune ups and troubleshooting.

    I'm having problems with my Mooneyes 0-15 liquid filled gauge. You can start the car up and fuel pressure reads right at 3lbs. As things warm up pressure falls to 0lbs. Roughly 5min time. Let the motor cool down and start over and the problem persists. Running low pressure electric fuel pump. Three different brand pumps same problem. Hook my master gauge to and problem goes away.

    @MMM1693
    all small like 50 Cent piece ones do that , just to verify
    Drain gauge, save solution /oil.
    install gauge test , gauge should stay steady .. then you can add oil back or discard

    I have this one, but I’m 1200 miles from my car and can’t tell you the size, but it might be what you’re looking for.

    I read why they do this , but I can not remember why , seem if Manufacturers know of issue why would they use the solution they do,
    I do not Recall AutoMeter the
    ProComp Liquid filled 2-5/8's or The Glow in Dark doing this ,

    The website says out of stock, but this is pretty nice in my opinion. A bit heavy on the logo but cooler than the alternatives I have seen.
