i would to know a good pressure gauge to put on the end of my fuel rail at the scrader valve the oil filled take time to desypher due to outside temps . aeromotive makes one that has no fluid and reads acuall psi . whats peoples thoughts?? i'd like to put it on end of fuel rail and maybe [T] it to keep scrader valve operational.

 

Look for some nitrous kits that have the schrader T to feed the system and have the other side for a pressure cutoff.

Check thunder racing for a 1 1/2" gauge (or so) and rotate if it'll have the female to adapt to the scrader port.
