3 PSI Fuel Pressure Gauge

My new tri-power set up requires very little fuel pressure ( 1 to 1 1/2 psi ). I am trying to find a pressure gauge that has a very small scale. Mostly finding 0-15 psi on the market. Does anyone know of someone selling these type gauges? I need small inline type, 3 of them.

Thanks

Unless you are running 3 separate fuel pressure regulators you should not need 3 gauges. A single gauge will do fine measuring pressure anyplace in the fuel line (post regulator).

What carbs are you running that require such little pressure?

For finding gauges like you want, Amazon. Search 15 PSI pressure gauge and take your pick. You can also search 10 PSI but the results are not as good. They even have some in the 5 PSI range. $20 for a liquid filled 3/2/3% gauge (3% tolerance at the ends of the scale and 2% at mid range)

1 psi? That is really low, as in not meant to be pushed very hard low.

You may want to consider a return line at a fuel pressure regulator which will help you set that 1 psi, yet give you quick volume when you open the throttles up to go.

My fuel rail is already set up for three gauges, because I am running a tri-power set up. My carbs are Holley 2110's.

My goodness but those are an old carb! AKA the Holley "BugSpray". Somewhere between a Stromberg 94/97 and a Rochester 2GC.
