Need help w/ elect fuel pressure gauge
To hook it to the fuel rail, i believe you'll have to unscrew the schrader valve inside then and some locktight to the threads to your conectors.
i think what you need is a -4AN female to a 1/4" NPT female coupler
-4 being the fuel rail side
I bought mine from Metco but im pretty sure you can get them from earls and NOS too.
