(Thanks Jeff) I just installed my Kilby gas tank skid and it is beefy and raises the tank 1" like claimed!
While I was at it I printed up Jeffy's Gas tank mod and went to work. In a 97TJ the tube is molded to the tank and 8" long inside the tank. So I cut it as close as I could get to the tank. Also the fuel gauge was past the red and there might have been almost 2 gals in the tank still.
So after I was done installing everything I went to Chevron and pumped 17.8 gals! Normally when the tank is that low I could get close to 13 gals in the tank, so it works!
So with almost 20 gals in the tank and 10 gals in gerry cans I should have plenty of fuel for some long trips!
