I am going to "Tap into" the hot side of the ENG 1 blade fuse with a 12 gauge wire, that will run through a stand alone 20 amp blade fuse. That way the ENG 1 circuit and the fuel pump will be protected. I case the ground wire from the LP runs to a bad ground, I will take another 12 gauge wire from the negative side of the pump, and run it to the negative battery terminal on one of the batteries. That will work untill I install a bottom feed 96 gallon " Transfer Tank" like all the ranchers out here have in their pickups, to make SURE that the pressure head in the tank will be MORE than able to feed the main injector pump. I'll take the stick tank in the truck, and throw it away.
