Description
Radium Fuel Tank Lock Ring, Chevrolet Corvette C8
Application: Chevrolet Corvette C8 (2020+) – RH and LH fuel tanks
Part Type: Fuel tank lock ring
Part Number: 20-1115
The 2020+ Chevrolet Corvette C8 OEM fuel tank lock ring has a large "cage" that is specific to the OEM fuel lines, so it cannot be used with aftermarket fuel fittings. The Radium 20-1115 lock ring replaces it with a design that clears aftermarket plumbing.
It is made from high-strength steel, so all removal tools can be used without warping or permanently damaging the ring, and it is powder coated to resist surface marring and oxidation. It is the same lock ring that is supplied with Radium's C8 fuel pump hangers.
Key Features
- Aftermarket Fitting Clearance: Replaces the OEM caged lock ring that will not clear aftermarket fuel fittings
- High-Strength Steel: Withstands removal tools without warping or permanent damage
- Powder Coated: Resists surface marring and oxidation
- Both Tanks: Compatible with both the RH and LH fuel tanks
