i bought a aftermarket one and bolted it to my frame rail just in front of my notch
its basic stuff man
all you need is a ground and ign power (so when you turn on your key the wire is hot)
i have a 15 gall fuel cell in the bed of my truck so all i have is a vent (off the top) just run it threw the bed
a return other fitting on the top (i capped one of the two lines off on the firewall behind the carb)
and a main fuel line to the electric fuel pump of the sump of the fuel cell
its easy once you do it the only bad thing my fuel gauge dont work but all i have to do is listen for a loud tapping sound and i know i got about 1 mile to find a gas station
