🔌 Function

The ring seals and positions a joint within the engine's fuel system so fuel is contained at the intended pressure and air is kept out of the circuit. Renewing it during service restores the sealing integrity of the assembly it fits into.

⚠️ Common Signs of Failure

• Fuel weeping, seepage or staining around the joint it seals
• Hardening, cracking or flattening of the ring from age, heat and fuel exposure
• Air drawn into the fuel circuit causing hard starting, rough running or stalling
• Loss of fuel delivery pressure or inconsistent fuelling
• Visible distortion, nicks or scoring on the sealing face after disassembly

🛠️ Service Notes

• Renew rather than reuse: rings of this kind seal or retain by being sprung or compressed into place and take a permanent set once fitted
• Clean the groove, register or bore the ring sits in and remove any burr or old sealing residue before fitting — debris in the groove stops a ring seating and is a common cause of a repeat leak
• Open or compress the ring only as far as it needs to go on; overstretching or twisting it during fitting distorts it permanently
• Check the ring is fully seated all the way round its groove or register, and the right way round where its faces differ, before closing the assembly up
