Rci 3 gal fuel cell

I have a new RCI 3 gallon fuel cell with foam and mounting tabs that I was going to use for my car but going to a use a 10 12 or 15 gallon instead . new at summit is 139.97 and that one don't have the mounting tabs so you need to use the mounting straps with it so that's a 37.97 more you have to spend to mount it. 125.00 + shipping it uses all 8 AN fittings.
