i just ordered the glacier diesel perfomance fuel system. the gfs-391 kit. fromt he instructions it seams like a straight forward install. anyone install these and have any tips. i says to drop the tank but my brother is going to help me, it will only take about 20 minutes to pull the bed off the truck so thats what we are gonna do. it feel it will make it easier to mount pump and run the wires and such with the tank in place so that i i can do the wiring nice a clean. being this kit leaves the factory pump and lines in place so you can use it still just incase. i was thinking of putting in a 3 way toggle switch on the inside of the truck so i can switch to either pump whenever i want. any tips or suggestions are welcome. thanks.
