I had one but had to remove it when I did a spring reverse on the rear and the rear diff hit it after that. I had plans to try to modify the tank and cut it down, but gave up on that and sold it a couple years ago. It was a pretty simple install, IIRC. The fuel line from the stock tank was cut and the 3 way solenoid valve installed in-line, with a line from the aux tank tieing into the extra port on the 3-way valve. The venting wasn't ran anywhere, which was done by the PO and may not have been correct. It did puke fuel if you overfilled it.
