Easy , a return fuel system you would run a wire to a relay from the switch, the relay would have a HEAVY gauge wire from the Batt to the relay then to the pump and a HEAVY ground wire to the pump

Then you would trick the fuel rail psi regulator to read 45psi , I will go into that another time because I dont tell everything on here and it doesnt seem others have caught on to this yet , makes a tuners life easier and safer on the engine for sure
