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 leaking fuel supply tube may present as a noticeable fuel smell around the engine or visible fuel seepage. If the tube becomes internally restricted, it can lead to a significant loss of engine power and rough running. Continued operation with a fuel leak risks fire hazards and can cause fuel starvation to the injectors, leading to engine damage.

Installation Tip

Ensure that the flare fittings on both ends of the tube are clean and free from damage before attempting to connect them. Avoid twisting the tube during installation, as this can create stress points and lead to premature failure.

Service Note

When replacing the fuel supply tube, inspect the fuel injectors and the injection pump for any signs of fuel leakage or damage.
