Quick Question, What size is the fuel pressure test fitting on the fuel rail, -4n?? Also if you unscrew the fitting from the fuel rail what is the size of the treads in the fuel rail?

the fitting is -4 AN
not sure on the threads......you will go crazy trying to find them though
if you need that port for something, just unscrew the valve in the tester
