Specification

Description

This is a fuel line assembly specifically designed for the CAT C7.1 excavator engine, with part number 464-7899 (4647899). It features a combined structure of stainless steel pipes and oil-resistant rubber hoses, designed to fit the original factory mounting points for direct replacement of old parts. The assembly integrates multiple precision bent pipes and fixed brackets, ensuring stable fuel delivery under complex working conditions and maintaining the reliability of the engine fuel supply system.

Advantage

OE-level compatibility: Fully matches the installation dimensions and interface specifications of CAT C7.1 excavators, enabling quick installation without additional modifications.
Weather and corrosion resistance: The main body is made of stainless steel, capable of withstanding harsh construction machinery environments such as moisture, dust, and corrosion, extending service life.
Robust and durable structure: The line combines integrally formed bent pipes with high-elasticity rubber sections, which can buffer engine vibrations and pipeline stress, reducing the risk of cracking.
Reliable sealing: The interface adopts precision threads and sealing design, effectively preventing fuel leakage and ensuring operational safety.

Performance

Working pressure range: Can stably withstand high-pressure pulses in the engine fuel system, with no deformation or leakage under pressure fluctuations.
Temperature resistance: Suitable for extreme operating temperatures from -40℃ to 120℃, maintaining pipeline flexibility and sealing under alternating hot and cold conditions.
Vibration fatigue resistance: Passes durability tests to withstand long-term high-frequency engine vibrations, ensuring no pipeline failure such as cracking or falling off.
Flow stability: The smooth inner wall and non-throttling design ensure stable fuel flow, meeting the fuel supply requirements of the engine under different working conditions.
