    I found with the 2rude and ET extreme I needed the Walbro to keep my Fuel pressure even. At high RPM's I n oticed the stock pump falling on its face. This is with a Riva ECU and 50's. Did not check with my 60's and LEs ecuu.

    When you add a RRFPR and your fuel pressure is 3-4 psi. below your base pressure at WOT ... Don't ask me how I know this

    What if your runnning a RRFPR, Rude 1, Riva ECU and 50# injecters? What would happen if I just wanted one for piece of mind? I know I need a LM1 or LM2 but dang, the Walbro is less $$ and I dont have to have it moddded for a bung. (JPipe bung winter project)
