PRODUCT DESCRIPTION

High-Pressure Resistant & Leak-Proof Design

This high-pressure fuel pipe OE KX3Q1-1104050 is manufactured to exact Yuchai engine specifications, using premium pressure-resistant material that withstands the extreme pressures of common rail fuel systems. The product features precision-machined connection ends that ensure a tight, leak-proof fit with both the common rail and injectors, eliminating fuel leaks and pressure loss. Its reinforced construction prevents deformation under high pressure and vibration, maintaining consistent fuel delivery to each cylinder. The 1:1 original dimensional design ensures seamless installation without modification, delivering reliable, leak-free performance.

Fuel Leaks & Pressure Loss

Truck operators often face critical issues with substandard fuel pipes, including material failure causing dangerous high-pressure fuel leaks; poor connections leading to pressure loss and reduced engine performance; and low-quality materials failing under heat and vibration. A faulty high-pressure fuel pipe compromises engine performance, creates fire hazards and leads to costly repairs. By choosing the genuine OE KX3Q1-1104050 pipe, users can instantly resolve these problems, ensuring consistent fuel delivery and eliminating leak risks.

OEM Quality & Rigorous Pressure Testing

As a key fuel system component, this high-pressure fuel pipe complies with Yuchai and Dongfeng’s strict quality standards and has passed comprehensive third-party tests for pressure resistance, durability and leak performance. Test data shows the pipe maintains structural integrity under maximum fuel system pressure, resists vibration fatigue and meets all applicable fuel safety specifications. Each unit undergoes 100% pressure testing and dimensional inspection before leaving the factory, guaranteeing complete consistency with original factory parts in performance, durability and fit. Backed by official Yuchai traceability codes, this product ensures 100% authenticity and reliable operation.
