The 2020+ Chevrolet Corvette C8 fuel tank lock ring has a large "cage" (shown) specific to the OEM fuel lines. It cannot be used with aftermarket fuel fittings. 

The bespoke Radium Engineering fuel tank lock is manufactured from high strength steel. This permits the use of all removal tools without warping or permanently damaging the lock ring. Furthermore, they are powder coated to resist surface marring oxidation.

NOTES:
1. This is the same fuel tank lock ring that is included with Radium Engineering C8 fuel pump hangers.
2. This fuel tank lock ring is compatible with both RH and LH fuel tanks.
