Electrical matters. The high flow pumps create more flow of both fuel and electrical current. So it is a good idea to upgrade the wiring to 10 or 12ga. As these pumps can draw 15 or more amps. I like to begin this wiring upgrade at the pump itself inside the gas tank. I mean, look at these tiny wires coming off the factory fuel pump pigtail. I'm pretty sure that is 16ga.. How is that gonna flow enough current to create all that fuel flow? So I like to replace the pins in that connector with something i can attach 12ga wires to. To bring all this robust power through the lid I like to take both power and ground pins in the connector and splice them together with the 12ga power wire from the pump. Like this..
