I didn’t want to drill holes in my trunk, mostly because there is already a gas tank right underneath it, so mounting in a convenient location was going to be a challenge. Trying to get up against the rear bulkhead is difficult because the floor angles up there. With those obstacles in mind I decided that suspending it would be the best course of action. As luck would have it the factory supplied me with some nice threaded holes on the bulkhead, the factory roll bar mount!
I fabbed up a bracket that would hold the tank just above the jack mount. I wanted it to go more to the right side, but the trunk hinge interfered with the top of the tank. While the back two tank mounts could be bolted to and supported sufficiently by my bracket, the front of the tank would need to be supported by legs. A stainless carriage bolt using an adjusting nut under the tank would let me fine tune the leveling of the tank. I also put felt pads under the carriage bolt heads to protect my trunk mat, and welded nuts under the bracket for the rear mounts for ease of installation.
I mounted an on/off valve on the discharge tube, and when it gets here, I will put a T fitting on the vent tube that goes from the tank to the filler neck and connect that to my valve. I will leave the valve closed because A. If the main tank was full then the auxiliary tank, since it is mounted higher, would overflow out the gas cap, and B. I’m not necessarily trying to extend range, just don’t want to run out of gas. When I’m on my way to get gas I will open the valve and let the old gas flow into the tank and then refill with fresh.
I even got lucky, and my jump start pack will just slide under it. After I get it all hooked up I’ll report back on how it works
