Installation Location: Designated bracket positions on engine cylinder head/cylinder block, near fuel filter, at fuel line branches, at wiring harness turning points, etc. Used for fixing fuel delivery pipes, return pipes, wiring harnesses and auxiliary pipelines
Wear & Leakage Risk
Causes: Insufficient clamping force leading to pipeline shaking, burrs on clip edges scratching pipelines, uneven sealing surface stress caused by aging/deformation
Symptoms: Scratches/bulges on pipeline surface, fuel oil seepage, fluctuating system pressure, hard starting/power loss
Solution: Replace damaged tube clip and pipeline; clean installation positions and pipeline surface; reinstall according to specifications; check interface sealing and reinforce
Wiring Harness Poor Contact
Causes: Tugging caused by insecure wiring harness fixing, loose plug, blocked signal transmission
Symptoms: Occasional engine shutdown, fault light on, unstable power, abnormal ECM signal
Solution: Replace tube clip and reinstall wiring harness; check plug for looseness/oxidation; replace related wiring harness or sensors if necessary
