I've got an RCI 2172A aluminum fuel cell for sale. 30" wide, 17" long, 7" deep. It's used but in great condition, no damage, cracks, or problems. Comes with the fill valve and cap, 0-90ohm GM style fuel level sender, and ports for feed, return, and vent, including a cap for one of them if needed. I bought it used and need a different size now. The mounting feet have been removed, but it should be held down with straps regardless, as the feet tend to break off anyway.
Costs $255 new, will sell for $175

Will trade for RCI 2162A
or possibly RCI 2161A
