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

Initial signs of a failing fuel tube may include a slight decrease in engine performance or a faint smell of diesel fuel. Continued operation with a compromised tube can lead to increased fuel consumption and rougher engine operation. Ignoring a leaking fuel tube poses a risk of fuel system contamination and potential fire hazards.

Installation Tip

Ensure the engine is completely cool before attempting removal to avoid burns and fuel spray. Do not overtighten the fittings, as this can damage the tube or the injector/pump threads.

Service Note

Inspect the fuel filter and injector seals for wear or damage when replacing the fuel tube.
