Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing fuel supply tube may initially present as intermittent engine sputtering or a slight loss of power under load. If left unaddressed, leaks can develop, leading to a persistent fuel smell, difficulty starting the engine due to fuel pressure loss, and potentially a rough or uneven idle. The primary risk is fuel leakage, which poses a fire hazard and can lead to significant engine damage if fuel delivery is compromised.

Installation Tip

Always use new sealing washers or O-rings when installing fuel lines to ensure a proper seal and prevent leaks. Do not reuse old hardware, as it may not provide adequate compression.

Service Note

Inspect the fuel filter and fuel lines for any signs of contamination or damage, and consider replacing them if they are near their service interval.
