A racing fuel cell is a flexible bladder inside a metal container, packed with foam, that replaces a stock gas tank to keep fuel contained in a crash. Bladders carry a dated certification label.
The bladder is the dated part, and who enforces the date varies. SFI’s spec list puts fuel cells under 28.1 at “5 Years + 2 Year Recert,” the competition bladder under 28.3 at five years, and the stock car bladder under 32.1 at five. Fuel Safe’s FIA-FT3 bladders are “not valid after date of five years from the original manufacture date,” or “seven years total if the fuel cell has previously been re-certified,” with recert available “only … within 60 days of the expiration date” — miss that window and you are buying, not recertifying. IMCA’s 2026 Modified rules ask for a “racing fuel cell … maximum 32 gallon capacity, must be in minimum 20 gauge steel container” and name no age limit. Read your rulebook, then read the label.
A bladder ages out on a date nobody looks at, and the two ways you find out are a tech official's flashlight and a wreck.
