On a side note, Carter are the only pump that I know that allows free flow threw it when off.
Back, way back, in the day they sold a trak-pak which was a inline pump.
Years later we put a carter back at the tank inline, it was wired to the n2o arming switch. We put a T fitting where the hard line turns to rubber right near the d/s footwell (A-body). The one side went to the mech pump and the other went to a n2o solenoid.
Worked well for someone who did not know what they were doing!! Maybe we just got lucky, never hurt the motor running a 150 shot.
Nice injection set up 😀 wish you had pics of it.
Carter always advertises the best numbers on pumps, but I've never tested them out personally.
