Anyone have a recommendation for a fuel pressure gauge that I can install in the engine compartment and leave there for a while? I don't need anything fancy. Just need something that will do the job and not leak and cause a fire hazard.

I am using this one

It seems to be a higher quality built item as opposed to completely cheap Chinese ones. Hope I am not kidding myself because a failure could be ugly.

Still using D-Jet? Get one with a 5/16" fuel line connection and clamp to the t-fitting on the stock fuel rail.

I have this for diagnosing various cars, and use an extended fuel hose when I want to monitor from inside the car.

My fuel rail doesn't have the t fitting. on it. (If I'm understanding you correctly). And fuel line is 7mm I think. Isn't 5/16" too big? I don't want to any chances with the line leaking fuel.

Your link didn't go to a specific gauge, but linked to a page with over 2000 results. Can you post a link to the specific gauge? Thanks

Hope this will help. Also depends if you have FI (28 to 31 psi) or Carb (2.5 to 3.5 psi). For FI you can get the 0-100 Psi and for carb maybe the 0-15 Psi.

same as above

this is the low pressure one for carbs. There is a 0-100 one for FI

@ ndfrigi: where can I locate the barbed fitting with a 1/8" female pipe opening?
thank you

Many fuel pressure gauges when mounted inside the engine compartment will give erroneously low readings after the compartment and the gauge heats up. You may be disappointed in an installation of this nature.

Is this a regulator/gauge combo unit?

Posted by: Krieger May 3 2021, 05:40 PM

That is a restrictor/pressure gauge from PMO. It is designed to convert a fuel injected 911 with a high pressure fuel pump to carburetors. It is marginal for use. I had one and have been much happier with a Holley fuel pressure regulator and an Aeromotive low pressure gauge.

I've used the PMO version in a couple cars.

Posted by: 930cabman May 3 2021, 05:51 PM

Does anyone make a gauge/pressure regulator combo reasonably priced? less than $50.
