When using a waterman setup, haisley sells the high speed check valve pair, a 50psi and 70psi piece.
I am using a DSR pump that does not have a return built in like the waterman. Fuel goes in, and fuel goes out the pressure side, only thing controlling pressure would be RPM or some type of regulator. I got to thinking about how this all works and I am now confused at how/where the high speed check valves would be used, or if I just need an external fuel pressure regulator with one of the check valves on the return from the injection pump.
