Fitting for fuel pressure gauge Does anyone know what fitting(s) I will need to install my AEM fuel pressure gauge? I would assume I just need something to go on the end of the fuel rail to push in the needle valve and have a female port to screw the pressure gauge into but I dont know much about those type fittings.

Well, I can tell you that a -6 AN female fitting is too large. I was told -6, its not. Must be -4 AN fitting. I bought a Adaptor the SHOULD have screwed onto the fuel rail, has a 1/8 NPT port, then bought a cap for the other end. Is it -4 AN to connect to the fuel rail?

You need a female -4AN to 1/8 NPT There are a few styles of fitting to do it depending on if you need to flow through the fitting or just go right into the gauge only...
I dont think there are any that will push in the valve for you, I removed mine..

I noticed you are in the process of building your setup.... I suggest this.... first off remove the schrader valve from the fuel rail end.
-4AN female to -6AN male adapter... then into a -6AN female to -6AN female then to the Aeromotive boost ref adjustable FPR, which has a return line to the tank.

acutally i think you guys are doing something completely different and removing the schradervalve off completely and replacing it with the an fitting. not sure if that would work on the lt1 style. but if anyone knows please let me know.
