So after taking 2 1500+ miles trips in my jeep in the last year and getting 300-320 miles pertank, i have decided im tired of stopping for fuel and want to install (not replace original) a 2nd auxillary fuel tank in my JKU. I have searched around the internet and saw the Gen kit and the price tag it comes with. so ive started pondering cheaper options in my head.
Luckly I have a 98 ZJ with a 22ish gallon tank that i started looking at.
So this is the plan- I know i need a tank, a switch, some wiring, a sending unit, and some hoses. I was going to relocate the muffler under the drivers side of the jeep and put the pick-n-pull ZJ gas tank with pump/sending unit in its place. I know i will need to cut my rear floor out for access and devise up some mounting brackets.
I was talking to my mechanicly inclined/electrician brother came came up with a few options-
Option #1:I told him i wanted both tanks independent and have each (stock OE and aux tank) pumps/sending units wired to the stock fuel gauge (activated by a switch between the two) running independently to the engine bay.
Option #2: He suggested to keep it simple and simply wire a switch to activate the second fuel pump when i need it and have the fuel lines from the 2nd tank pour into the OE gas tank to refill it.
before I start this endevor: can any one see any problems i would run into with the 1st or second option? This will be my first go at anything fuel related on a fullsized vehicle.
