The ATL Fuel Cells FM-UB-020 is a pre-cut replacement foam insert designed to fit a 22-gallon fuel cell with interior dimensions of 25 x 25 x 8.5 inches. This reticulated (open-cell) foam baffling block is a direct drop-in replacement for worn or damaged foam in compatible ATL fuel cell bladders and containers.

ATL's safety foam baffling serves a critical dual purpose inside any racing fuel cell: it suppresses explosion risk and dampens fuel surge and sloshing under high-G cornering, braking, and acceleration loads, while simultaneously supporting the flexible rubber bladder within its container. Keeping the foam in good condition is essential to maintaining the full safety performance of your fuel cell system.
