JAZ Products maintains their own equipment and molds, producing only the highest quality fuel cells. Their Circle Track Fuel Cells are molded in a seamless cross-linked polyethylene outer shell for exceptional quality over the competition. Each circle track fuel cell features a D-ring bail handle cap assembly with check valve vent or IMCA approved fill valve with check valve flapper. Available with or without foam, JAZ only uses the best safety foam on the market, which has up to a 10x longer service lifespan than that of other non-fuel approved foams. Designed specifically for circle track applications, the fuel pickup hose is routed directly to the right rear corner of the cell to maximize fuel pickup. All circle track fuel cells exceed SFI 28.1 and are accepted by most sanctioning organizations.
