🔌 Function

The O-ring sits in a groove and is compressed on assembly, deforming to fill the gap between mating surfaces so fuel cannot escape and air cannot be drawn in. Its elasticity maintains that seal under pressure and vibration.

⚠️ Common Signs of Failure

• Fuel weeping or staining at the joint
• Air drawn into the fuel system causing hard starting or rough running
• Hardening, cracking or permanent set on removal
• Swelling or softening from fuel contact
• Nicks or cuts from incorrect installation

🛠️ Service Notes

• Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
• Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
• Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
• Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
• Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
