It sounds like he already has the pumps wired correctly --> Using 12v relays (from the battery) triggered by the fuel pump ecu. I ran ONE of my walbro pumps through the stock pump wiring, and for the other walbro, I did the relay method triggered by the pump ecu.

I've seen people run 2 walbros off stock wiring and get away with it because walbros draw half the current than stock pumps. You could also replace the stock wiring (to the pumps) with thicker gauge wire.

On another note, I thought there were a few issues of people losing FP on a hot day after the car has warmed up. The walbros would be flowing so much fuel that it would heat the FPR and cause a drop in FP. I have not seen this problem on my setup though.
