i have the ATL 12 gallon "well cell". Still need to plumb it and fabricate bracket. I wish it was shorter and wider to fit flush in the wheel well so i could make a flat panel to cover it flush.. I called ATL but too much $$$ to fabricate a new one.
I have not seen that one on demon...i wonder what the difference in dimensions are.
purpose..relocate fuel tank to lower position...lower center of gravity..figure 12 gallons of fuel and tank weighs about 95-100lbs..also has crash/leak resistance...lighter ..weighs 18lbs...i dont know what the stock fuel tank weighs.
