On my 20 gallon factory tank it was just held in place by the skid plate, I believe the 15 gallon is the same way. The tank is strapped to the skidpan and the skid pan is taken off the frame from a row of bolts along the rearcrossmember and another few across the next frame rail towards the front.
Do you guys know if its possible to remove just the top strap on a poly tank without dropping the skid and tank? I know how to drop the tank, I just want to remove the strap only if that's possible, in order to paint it. Thanks
to the OP:I just played with mine, I have the 20 gallon factory tank and it take 4 bolts at the back and 3 towards the front to lower it. My bet is if you put a jack under it lower it a few inches you will be able to reattach your sender wire without having to mess with taking off the filler and vent hose. If you do end up having to deal with the hoses save yourself the headache and take off the 3 screws that hold on the filler cap assembly and disconnect the hoses there. As with any cj I applied plenty of penetrating oil to all the bolts/screw first.
