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?
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).
yes, i was thinking of that as an option.....just thought that perhaps there was an elbow with the pin depresser in it.
Most gauge ports are a dash -3 /-4 (exact size escapes me at the moment) just use the elbow and go to local hardware store and get a jic cap for natural gas fittings. Any ace hardware will have a selection of it. 5 bucks or less.
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
Nice simple setup and the good thing is if there's any issues you can remove it all and re install the Schrader valve into original fitting. I haven't ran mine yet but I used the same setup.
