• Seamless steel pipe body with uniform wall thickness, good pressure resistance, not easy to crack under vibration.
• Optimized bending design, smooth fuel flow, reduce flow resistance and avoid fuel supply shortage.
• Internal and external anti-corrosion coating prevents rust inside the pipe, reduce impurity entering fuel system.
• Standard joint size, good sealing performance, effectively prevent fuel leakage and air suction into oil circuit.
• Direct replacement for original part, simple installation, no extra cutting or welding work.
• Stable fuel supply protects fuel pump and injector, reduce fuel system failure rate.

FAQ 

Q1：What symptoms indicate the oil inlet pipe needs to be replaced?
A1：Fuel leakage at joints, pipe wall rust through, pipe body cracks, air entering the oil circuit. Air intake will lead to engine power drop, difficulty in starting and flameout during operation.

Q2：What points should be noted during installation?
A2：Clean the inside and outside of pipeline, check the sealing ring integrity. Tighten the connector evenly. After assembly, fill fuel and check for leakage. Do not use aging sealing parts.

Q3：What are the main causes of oil inlet pipe damage?
A3：Long-term vibration fatigue; internal and external corrosion; external collision abrasion; aging of sealing fittings.

Q4：Can small cracks on the pipe be welded for repair?
A4：Not recommended. Welding will change pipe material property, repaired position is easy to crack again under vibration, fuel leakage has fire risk, better replace with new pipe.

Q5：How to inspect the oil inlet pipe in daily maintenance?
A5：Check pipe surface for rust and cracks, inspect connector for oil seepage. Clean dirt around pipeline regularly, check sealing ring aging condition.

Q6：What harm will oil circuit air intake bring?
A6：Air entering oil pipeline will cause unstable fuel supply. Engine power declines, hard to start, and may suddenly stall during work, bringing safety risk.
