The early CPI 4.3's (91 to 95) have a cool fitting in the back of the intake that can easily be adapted to become a TBI fuel pressure gauge port.

Comes with Schrader valve fuel pressure test fitting and female inlet threads to match the fuel inlet line and a barbed fitting on the other side.

I haven't used it yet but I am going to have the local hydraulic shop solder on a -06 male fitting to make it easy to integrate into the fuel supply line.

I planned on tapping the threads in the fuel pod for standard pipe threads so I can use -06 AN fittings on the throttle body and route the test port to where it is easily accessible. From my measurements it looks like 1/4" pipe and 3/8" pipe threads are just about a match for the metric fitting openings.
