fuel rail pressure adapter

[94yellowgt5.0]

hi i just bought a steeda fuel pressure gauge for my my fuel rail and i was wondering what size fitting adapts the gauge to the fuel rail because the fitting that comes in the fitting is a one way valve and its not letting the gauge read any fuel pressure and i know the gauge works because i tested, also there is two fittings that come in the kit, one is a adapter for the fuel rail but the other is just a 90 degree bend all i want is one fitting that mounts the fuel pressure gauge to the fuel rail. I know the fuel gauge is 1/8" but what is the fuel rail? I also want a brass fitting for the adapter not aluminum, so does anyone know where i can get a fitting from? thanks in advance

Schraeder valve is 1/16" NPT. You can buy a 1/16" NPT to -3AN or -4AN adapter from Summit. It's manufactured by NOS I believe.

Or a 1/16" NPT to a 1/8 adapter.

The unit you are looking at by the description appears to thread onto the schraeder valve so the adapter isn't necessary. The 1/16 to 1/8 NPT is as you described. 1/16 male to 1/8 female. That was if you were removing the schraeder valve.

yea i'd be removing the schrader valve because the adapter that screwed onto the schrader valve stripped.
