Hey guys has anyone yet rerouted there riva fuel pressure regulator
Im ready to drop a fuel rail in and im gonna divert my fuel intake so that my regulator comes after the rail. I was wondering if anyone has done this and have they seen any differences in it thanks tim.

The idea would be that you should get more even pressure across each injector. This is how I have mine setup; pump, in one end of fuel rail, out other end of fuel rail to reg, from reg return back to tank.

This is how Malvin sets his Turbo tech rails up. I have done this also. Just cut off the end of your stock rail ( just the loop end) and tap it. Run that end to the rpr
Or buy a billet rail.

The advantages to running the regulator after the fuel rail and having a return line is to keep the fuel charge as cool as possible. This is the same reason automobiles are plumbed like this. It does also help to keep even pressure across all the injectors but isnt the main reason for doing it. With a steady flow of fuel moving all the time it keeps the fuel from sitting in the fuel rail, becoming heat soaked and rising in temperature.
