I have not done this. As seen in my recent first start video the engine started and ran fine. Is cutting this wire a requirement and if I don't cut it what do I risk?
You only do that if you want to use the RF fuel pump circuit including the relay, inertia switch, and +12V wire back to the fuel pump. If you've already wired directly to the fuel pump from your Holly Sniper EFI system, technically not required to run your fuel pump. Only caution I'll cite is whether you have an inertia switch with your setup. It's a safety function that shuts down the fuel pump in the event of a hard collision or rollover. The RF fuel pump circuit wires that relay to ground through the inertia switch. If the switch opens, ground is broken, and the fuel pump circuit's power is cut off. Something to think about.
