I've used this tank for circle racing for several years and has worked well especially if you're trying to achieve a center of gravity type setup. No fuel slosh here. I am upgrading to a dual stacked tank since the boat will become a dual purpose boat.

All the mounting brackets come with it. Even though it was mounted to one stringer, it was pretty solid. I dont know the exact capacity, but my best guess is 7 gallons. Can be used as a dry sump tank too. It has the fill cap and 4 bungs on top. $250 plus the ride.
