## 🔌 Function

Seals a fuel joint by being squeezed into its groove, blocking the leakage path between the two parts.

## ⚠️ Common Signs of Failure

-   Diesel weeping or a fuel smell at the joint
-   Air drawn into the fuel system causing rough running
-   O-ring flattened, nicked or twisted on removal
-   Ring hardened or swollen where fuel has attacked it
-   Groove or counterface scored so the ring cannot seal

## 🛠️ Service Notes

-   The gasket kit already contains this ring, so check whether the kit is better value when other seals in the same joint are due
-   Fit new every time the joint is opened, lubricate lightly with clean fuel, and check the groove for burrs first
