I have a 402 LS2 in my 2002 Firehawk, it has Fast fuel rails on a Fast intake. I am trying to find out what fitting I need in order to mount a small Holley fuel pressure guage on the drivers side front fuel rail where the crossover line goes. I dont know what size the fitting is on the guage, it's the standard 120 psi guage. Any help would be appreciated. Thanks.
