Re: Fuel rail mounted fuel pressure gauge
I forgot to ask before..... is there a thread sealant used, or just tighten it firm? Teflon tape?

Re: Fuel rail mounted fuel pressure gauge
old thread, but in the quest to get my rebuilt engine running i decided to mount a FPG on the fuel rail. Bought the parts as suggested; however, the elbow (361-923104) does not have a provision to push the schrader pin in.....wrong part number?

Re: Fuel rail mounted fuel pressure gauge
Did you determine why you hve no pressure. I'm having same issue suddenly. I hear pump prime and cut off, but test gauge shows like 2-3lb of pressure (if that).

Re: Fuel rail mounted fuel pressure gauge
However, for as cheap as 0-100 psi transducers are now days and gauges being so cheap. Just do an electric gauge and not have to mess with fuel getting dripped on the intake. Sensos have for better and cheaper. Added benefit is if your ecu has an extra 0-5 volt sensor input that's scalable you can data log it when tuning. Pretty sure the 7727 does. Can't speak for the f body ecus
