@Outsane , here's a pic of the location where I chose. It's mounted to the frame member that the front of the aux tank is mounted to, above the panhard rod. Looks like yours is mounted to the brace that's part of the floor or body of the 80. If you measure up from the bottom of your aux tank, you'll see that the body mount is like twice the distance which makes the pump work outside it's designed perameters. The pump initially works, but will tend to fail with frequent and extended use. That's been my experience with tank installed for over 2 years, now.
