Retro Locking Fuel Cap, Not for RV-12/12iS

This fuel cap will fit in an original/legacy kit tank flange (typically, this means RV kits prior to RV-14 and which were shipped prior to 2017) to provide a locking cap on a completed tank. Requires some tank sealant ( Fuel Tank Sealant, 3.5 ounces ) to bond the new flange within the old flange.

Will reduce the opening size, so larger gas nozzles may not fit (most are OK). New diameter is 1 3/8".

This cap is UNVENTED and will not work on the RV-12, nor with the newer T-00007 flanges that have been used in RV wing kits shipped since mid-2017.
