Question about fuel injection from a newbie

I didn't think about him maybe having the regulator in the wrong place. HAS to be AFTER the fuel rails, controlling return only.

Surely his battery or batteries is/are in the trunk. I let my FAST ECU control my fuel pump relay, just like a factory vehicle. My relay is back there too. All 10 gauge wire from my batteries to the relay, then to the pump, and a ten gauge ground from the pump back to the battery's ground terminals. My batteries are grounded directly to the engine, with a long, large gauge ground cable. I have a ground cable to the body too. My battery cables have all terminals soldered on. I've logged my fuel pressure. Never changes. Solid at 60 psi.
