🔌 Function

The gasket forms a leak-tight seal between two mating faces in the engine's fuel system, preventing fuel leakage and maintaining the pressure integrity of the circuit. Because it is compressed on assembly, it is treated as a replacement item whenever the joint is separated.

⚠️ Common Signs of Failure

• Visible fuel seepage, wetness or staining around the sealed joint
• Fuel odour in the engine compartment
• Air drawn into the fuel system causing hard starting, rough running or loss of power
• Hardened, cracked, flattened or torn gasket material found on inspection
• Repeated need to retighten the joint fasteners to stop a leak

🛠️ Service Notes

• Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
• Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
• Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
• Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
• Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
