We used a RRE package for a while,tandem pump with injectors.You'll need to use a 60 psi regulator.One outlet feeds your fuel shut off valve. The bypass outlet return's to tank.
My concern is the pressure, I read some people saying it doesn’t create enough pressure. Our class is switching from carb to injection and I wanted to see if I could get away with the pump I have now. Thank you it’s good to know it can be used
I ran one on our sprint car, I took the spring out of the pump and ran my low speed & high speed off the pump, just like my Hilborn, no issues whatsoever
