They were hooked into the fuel system with a floor mounted manual 3 way tap/selector.

Mounts were long 1/2' dia bolts that ran down through the tank.

Fitted in 1970, still there not leaking in 2018.

They were just over 15.5 US gallons each.
Speaking from experience I guarantee those tanks are very rusty inside. Stay away from them. You'll get a lot of crap in your gas using them. I would use them. I had them and the best option is to either stay with your existing in cab tank or get a new rear under bed tank.
