Product Introduction

• Structure: A complete set of precision-bent, high-strength steel pipes with a corrosion-resistant zinc-plated surface. Each pipe is fitted with high-pressure sealing nuts and washers to ensure a leak-free connection. The assembly is designed with brackets and clips for secure routing and vibration isolation.

• Performance: Transmits high-pressure fuel (up to 1500 bar) from the injection pump to each injector with minimal pressure loss. The rigid steel construction and precision bending ensure durability and resistance to vibration, preventing fatigue failure in harsh operating environments.

Core Function

1. High-Pressure Fuel Delivery: Transports precisely metered, high-pressure fuel from the injection pump to each cylinder’s fuel injector.

2. Sealing & Vibration Resistance: The precision-machined fittings and robust construction ensure a leak-free seal and minimize vibration-induced wear.

3. System Integrity: Maintains the fuel pressure required for optimal injector performance, ensuring efficient combustion and engine power output.

Key Features and Benefits of High Pressure Fuel Pipe 330-1104010

Precision-Engineered for Yuchai Diesel Performance

Every High Pressure Fuel Pipe 330-1104010 Yuchai is cold-drawn from seamless high-carbon steel tubing, then precision-formed to match OEM bend radii within ±0.5 mm tolerance. This ensures a drop-in fit that eliminates installation guesswork and prevents stress fractures from misalignment.

• Burst Pressure Rated Above 2,500 bar – Provides a generous safety margin over the operating pressure of Yuchai YC6 series fuel systems, reducing roadside failure risk by up to 90% compared to aftermarket alternatives.
• Internal Surface Finish ≤ Ra 0.4 μm – Mirror-smooth bore minimizes flow turbulence and prevents micro-particle entrapment that could damage injector nozzles.
• Anti-Corrosion Phosphate Coating – External zinc-phosphate treatment resists moisture, road salt, and diesel residue corrosion, extending service life to 200,000+ km under normal operating conditions.
• Vibration-Resistant Connection Geometry – Forged cone-and-sleeve end fittings absorb engine vibration harmonics, maintaining torque integrity at both the pump and injector interfaces.
• 100% Pressure-Tested Before Shipment – Each pipe undergoes hydrostatic pressure testing at 2,000 bar for 60 seconds, ensuring zero leakage leaves our facility.

Technical Specifications – High Pressure Fuel Pipe 330-1104010 Yuchai

Vehicle Application Scenarios

The High Pressure Fuel Pipe 330-1104010 Yuchai serves as a direct replacement across multiple heavy-duty platforms powered by Yuchai YC6 series diesel engines. Here’s where this component works hardest:

• Long-Haul Logistics Trucks – Vehicles running Yuchai YC6L and YC6MK engines in DONGFENG and FOTON chassis that cover 300,000+ km annually depend on leak-free high-pressure fuel delivery to maintain fuel economy targets.
• Construction and Mining Dump Trucks – SHACMAN and SINOTRUK platforms equipped with Yuchai powertrains face extreme vibration loads; this pipe’s forged end fittings prevent loosening under continuous off-road hammering.
• Municipal and Public Transit Buses – City buses running Yuchai YC6G and YC6J engines require fuel pipes that resist thermal cycling from frequent stop-start duty cycles in urban traffic.
• Agricultural and Industrial Machinery – Stationary and mobile equipment using Yuchai engines in generator sets and agricultural tractors benefit from the corrosion-resistant coating in high-humidity environments.

Whether your fleet operates across Southeast Asian highways, African mining roads, or South American agricultural zones, this fuel pipe is built to endure the conditions your Yuchai engines face daily.

Customer Case Study – High Pressure Fuel Pipe 330-1104010 Yuchai in Action

A major fleet maintenance company in West Africa managing over 1,200 DONGFENG trucks equipped with Yuchai YC6L280 engines faced recurring fuel pipe failures sourced from local aftermarket suppliers. Cracked pipes and leaking fittings were causing an average of 14 roadside breakdowns per month—each one costing approximately $800 in towing, labor, and lost cargo delivery time.

After switching to the High Pressure Fuel Pipe 330-1104010 Yuchai supplied by METTLEAD, the fleet experienced the following results over a 12-month evaluation period:

• Fuel pipe-related breakdowns dropped from 14/month to fewer than 1/month – a 93% reduction.
• Procurement cost per unit decreased by 35% compared to their previous branded-import channel, thanks to METTLEAD’s factory-direct model.
• Average service life exceeded 220,000 km before scheduled replacement, surpassing the 200,000 km benchmark.
• Zero injector nozzle failures attributed to pipe-related contamination during the evaluation period.

The procurement director commented: “We tested METTLEAD’s high pressure fuel pipe 330-1104010 Yuchai on 50 trucks first. When zero pipes failed in 8 months, we converted our entire fleet. The quality speaks through the data.”

Frequently Asked Questions – High Pressure Fuel Pipe 330-1104010 Yuchai

What makes the High Pressure Fuel Pipe 330-1104010 different from generic aftermarket fuel pipes?

Generic aftermarket pipes are often produced from welded tubing with inconsistent wall thickness. The 330-1104010 uses seamless cold-drawn steel with a controlled inner bore finish of ≤ Ra 0.4 μm. This seamless construction eliminates weld-point weak spots that crack under cyclic high-pressure pulsation, while the mirror-smooth bore prevents fuel contamination particles from lodging inside the pipe and migrating to your injectors.

Is this High Pressure Fuel Pipe 330-1104010 Yuchai compatible with common-rail fuel systems?

The 330-1104010 is specifically designed for Yuchai mechanical and electronic unit pump fuel injection systems found in YC6 series engines. If your engine uses a Bosch or Denso common-rail system, the pipe geometry and end fittings differ. Contact our technical team with your full engine model number, and we will confirm the correct high pressure fuel pipe part number for your application.

How should I store High Pressure Fuel Pipes before installation?

Store in original packaging in a dry, clean environment away from direct sunlight. The protective end caps must remain in place until the moment of installation to prevent dust and moisture ingress into the bore. If stored for more than 6 months, inspect the phosphate coating for any signs of oxidation before fitting. Avoid stacking heavy items on top of pipes, as even minor bending deformation can alter flow characteristics and stress distribution.

What torque specifications should be applied to the High Pressure Fuel Pipe 330-1104010 end fittings?

Follow Yuchai’s official torque values: typically 25–30 Nm for the pump-side connection and 20–25 Nm for the injector-side nut. Always use a calibrated torque wrench—over-tightening crushes the sealing cone and causes hairline cracks, while under-tightening allows diesel weeping that accelerates external corrosion. Retorque after the first 50 hours of operation as part of standard Yuchai maintenance protocol.

Can METTLEAD supply complete fuel pipe sets for all cylinders of my Yuchai engine?

Yes. We stock the full set of high pressure fuel pipes for 4-cylinder and 6-cylinder Yuchai engine configurations. Ordering complete sets ensures matched manufacturing batch quality and consistent pressure performance across all cylinders. Contact us with your engine serial number for a complete set quotation.

What is the typical lead time for bulk orders of High Pressure Fuel Pipe 330-1104010 Yuchai?

Standard stock orders of up to 500 pieces ship within 3–7 business days. Bulk orders exceeding 2,000 pieces typically require 15–20 days for production and quality testing. We maintain a rolling safety stock for this popular part number, so most procurement managers receive their shipments faster than expected.
