Product Features

• Structure: Made of high-precision cold-drawn seamless steel pipe with a thickened wall, precision-machined at both ends with a tapered sealing surface and matching the injector and fuel injection pump interfaces. Equipped with a fixed clamp to prevent pipe vibration and wear.

• Performance: Withstands high fuel injection pressure (up to 1000+ bar), ensuring stable fuel delivery without leakage or pressure loss. The seamless steel pipe has excellent fatigue resistance and corrosion resistance, adapting to the harsh working environment of the engine.

• Design: 100% interchangeable with the original part, ensuring precise matching with the first cylinder injector and fuel injection pump of XCMG construction machinery equipped with D6114/D9 series engines.

Core Function

1. Fuel Delivery: Transports high-pressure fuel from the fuel injection pump to the first cylinder injector, ensuring precise fuel supply for combustion.

2. Pressure Stability: Maintains stable fuel pressure during injection, supporting efficient and complete combustion of the engine.

3. Vibration Reduction: The fixed clamp design reduces pipe vibration, preventing fatigue damage and leakage risks during engine operation.

High-Pressure Fuel Pipe D26-001-35 SHANGCHAI – OEM-Grade Fuel Injection Line for Heavy-Duty Diesel Engines

When your SHANGCHAI D-series engine demands precise fuel delivery at extreme pressures, every millimeter of pipe integrity counts. The High-Pressure Fuel Pipe D26-001-35 is engineered to channel diesel from the injection pump to each cylinder with zero tolerance for leakage, pressure drop, or fatigue failure. Sourced directly from METTLEAD Truck Parts’ quality-controlled supply chain in China, this fuel pipe delivers OEM-equivalent performance at a factory-direct price that protects your procurement budget.

Why This High-Pressure Fuel Pipe Matters to Your Fleet

A compromised high-pressure fuel pipe doesn’t just reduce engine efficiency — it threatens the entire combustion cycle. The D26-001-35 fuel pipe is precision-formed to maintain consistent fuel atomization pressure, ensuring your SHANGCHAI engine runs at peak thermal efficiency while meeting emission standards.

• Pressure Integrity: Withstands operating pressures exceeding 1,600 bar without micro-cracking or deformation, keeping fuel delivery stable across all RPM ranges.
• Vibration Resistance: Cold-drawn seamless steel construction absorbs engine vibration without fatigue fracture — a common failure point in inferior aftermarket pipes.
• Precision Fitment: Manufactured to OEM dimensional tolerances (±0.05 mm on critical bends), eliminating installation rework and reducing mechanic labor time.
• Corrosion Protection: Phosphate-coated exterior resists moisture and road salt, extending service life in harsh operating environments.
• Fuel Compatibility: Inner bore surface finish (Ra ≤ 0.4 μm) minimizes flow turbulence and resists degradation from biodiesel blends up to B20.

Frequently Asked Questions – High-Pressure Fuel Pipe D26-001-35

What causes high-pressure fuel pipes to fail prematurely?

The most common failure modes are vibration-induced fatigue cracking, corrosion from moisture ingress at connector seats, and internal erosion from contaminated fuel. The D26-001-35 addresses all three through seamless cold-drawn construction, phosphate surface treatment, and a mirror-finish inner bore that resists particulate abrasion.

How do I verify this fuel pipe fits my specific SHANGCHAI engine model?

Cross-reference the OEM part number D26-001-35 with your engine’s fuel injection system diagram. This pipe is designed for SHANGCHAI D-series engines using mechanical or electronically-controlled inline injection pumps. If you need confirmation for a specific engine serial number, our technical team can verify compatibility within 24 hours.

Can this fuel pipe handle biodiesel or alternative fuel blends?

Yes. The internal surface finish and steel grade are compatible with biodiesel blends up to B20. For higher concentrations, we recommend consulting your injection pump manufacturer’s guidelines, as seal materials in the pump may have different tolerances than the pipe itself.

What is the recommended replacement interval for high-pressure fuel pipes?

Industry best practice recommends inspecting high-pressure fuel pipes every 3,000–5,000 engine hours and replacing them at the first sign of surface pitting, connector seat wear, or external corrosion. Preventive replacement during major overhauls (typically every 10,000–15,000 hours) eliminates the risk of in-service failure.

How does METTLEAD ensure dimensional accuracy on bent fuel pipe sections?

Each pipe is formed using CNC tube-bending equipment calibrated to OEM bend radii and angles. Post-bending inspection uses 3D coordinate measurement to verify that every bend point falls within ±0.05 mm of the original specification — ensuring drop-in fitment without adapter modifications.
