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.
Summit carry’s a gauge that goes to 10psi https://www.summitracing.com/parts/...MIn_6sr7TFkgMVES1ECB3WhSUhEAQYBSABEgIaZPD_BwE
Wish ****s Hot Rod Carbs was still around. He had the best low pressure gauge around. I have one on my 39.
If you can live with 1-3/4"dia there is this 10# max gauge. https://nystromperformance.com/products/stromberg-fuel-pressure-gauge
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.
I just bought a mooneyes 0-15 small gauge from Affordable Street Rods for about $52 shipped within a few days.
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.
