It needs to be wired to the keyswitch.
You can also put a toggle switch inline, and turn it on and off manually.

electric fuel pump is in that gas tank. you can do this 2 ways. one is take the bed off. un hook all your wires and remove the bolts out of the bed then get 3 buddies and remove the bed. so you can get to the top of the tank to get the fuel pump. or you can get a floor jack and support the tank and remove the tank straps and slowly ease the tank down so you can unhook the wires and hoses. then remove the tank all the way and work on removing the pump.
