This kit was perfect for replacing the O-rings in the Newton retrofit locking fuel caps for an RV-4. My caps were leaking in flight with full tanks. There are no instructions or diagrams included, or available from ACS, to show how to disassemble the fuel cap, which is the reason for 4 stars instead of 5. Disassembly involved prying / bending the four (4) red plastic locking tabs away from the center post, (the key should be in the locked position). I used 4 small screw drivers for this. The red plastic cap then slides off and the cap can be disassembled to replace the O-rings. The red plastic cap is replaced with the new one that is included in the kit.
