I have one of the fuel pressure gages like GM uses. It connects to an -AN fitting with a schrader valve in it on the fuel rail. I would like to add a pressure port to my rail that can use this type of gage.
I have seen the ones that mount in-line but I was hoping to thread a fitting into my Ross fuel rail. Ideas?
Thanks,
Scott

Re: Fuel Pressure Port/Tap
I searched high and low for these and came up empty. A trip to the U-Pull-It yard and I found what I wanted. I did not check the year but the older 2.8 and 3.1 GM V6s had a pressure tap threaded into an aluminum rail. The tap looks like it is stainless!! The GM fuel rails had the pressure taps but a majority of them are either welded in or made into the rail such that the only way to get them out was to cut.
The one I got threads in with a standard thread - 5/16" - 18. Even better, the guy at the wrecking yard gave them ( I picked up four) to me for free!!
I never liked the idea of a permanent gage on the rail. The thought of that leaking scares me. This tap is pretty simple and if you have an old low side gage/hose from an R12 refrigerant manifold gage set, it can work too.
