Radium R11A Replacement Fuel Bladder 10.5 Gallon Spare Tire | Universal (20-0651)

Your certification expired, not your fuel cell. Replacing the bladder puts the car back on the grid without buying the whole assembly again.

The Radium Engineering R11A replacement fuel bladder, 10.5 gallon spare tire is the certified heart of the RA-series spare tire well fuel cell, supplied with fresh FIA and SFI paperwork and its own serial number. FIA and SFI certifications run five years from date of manufacture, so a cell that is otherwise perfectly serviceable becomes ineligible for competition on the calendar rather than on condition. This bladder resets that clock. Made from a special polymer resistant to every fuel type, including gasoline, diesel, AV gas, E15, E85, ethanol, and methanol.

What You'll Feel

• A compliant cell again for a fraction of a full replacement
• Fresh five year FIA and SFI certification with serialized paperwork for tech inspection
• Pre-cut explosion suppressing anti-slosh foam included
• Fuel compatibility across every common race fuel

Features

• 10.5 gallon bladder shaped for the RA-series R11A spare tire well cell
• Unique serial number with FIA and SFI certifications
• Special polymer resistant to all fuel types
• Fuel cell foam included

The Details

The spare tire cell is a distinct shape, not simply a larger 10 gallon unit, so its bladder is specific to that cell. If your cell is the standard 10 gallon RA-series, the 20-0650 is the correct bladder instead. This is the bladder only: it cannot be used without the bladder can and lid, and the outer can, lid, nut ring, and fasteners all stay from your existing assembly. If the can is damaged rather than the bladder, the 20-0671 replacement spare tire can is the matching part.

Kit Includes

• Fuel cell bladder
• Fuel cell foam
• FIA certification and SFI certification

Applications

Important Notes

• Not compatible with Radium Fuel Safe series fuel cells
• Not interchangeable with the standard 10 gallon bladder (20-0650)
• Cannot be used without the bladder can and lid; this is a service part, not an alternative to a complete fuel cell
