Fuel Line

    information to be updated

The Fuel Line is the critical fluid pathway that transports fuel from the tank to the engine or other combustion devices. It performs functions such as pressurization, filtration, and distribution, and is widely used in power systems such as automobiles, aviation, marine vessels, and construction machinery.

Product Features:
Utilizing high-performance materials that are resistant to corrosion, high temperatures, and high pressures, the Fuel Line ensures leak-proof and corrosion-free operation even under extreme operating conditions.
It includes subsystems such as low-pressure and high-pressure delivery pipes, filters, pressure regulators, and fittings, forming a compact, modular piping network for easy on-site assembly and maintenance.
O-rings, bellows ends, or specialized sealing gaskets provide a reliable seal, preventing fuel leakage and impurities from entering.
Pre-filters, fine filters, and sedimentation buffer filters are installed before the fuel enters high-pressure components to remove particles, moisture, and paraffin, improving fuel quality and protecting the injection system.
A variety of quick-release, leak-free connections are available, including threaded, snap-fit, compression fittings, and DOT SureLock, facilitating rapid replacement and maintenance.
The selection of high-strength, lightweight materials and optimized pipe diameters reduces overall weight, improves fuel economy, and complies with increasingly stringent emissions regulations. Complying with ISO4413 and other safety standards, it has anti-vibration and anti-shock design to ensure stable operation in vibration and shock environments

Fuel Line Industry knowledge
In the field of power equipment such as automobiles, aviation, and construction machinery, the?fuel delivery system?is the "power blood vessel" that ensures the stable operation of equipment. However, the industry has long faced three core pain points: first, pipelines are prone to leakage and corrosion under extreme working conditions (high temperature, high pressure, strong corrosion), which can cause equipment failures and even safety hazards; second, impurities and moisture in fuel can easily block the precision injection system, reducing fuel combustion efficiency and significantly increasing exhaust emissions; third, traditional pipelines have low integration and poor modularity, resulting in time-consuming on-site assembly and later maintenance, and the excessive weight of pipelines directly affects the overall fuel economy of equipment. JIATIAN's fuel line system is developed specifically for these industry pain points, with the core technical positioning of "corrosion resistance, high sealing, modularization, and lightweight". It integrates multi-stage filtration, various types of leak-proof connections, and exclusive anti-vibration and anti-impact structures. It not only fully meets international safety standards such as ISO4413, but also can accurately adapt to the harsh operating requirements of power systems in multiple fields, providing a full-scenario fuel delivery solution for the industry.

Core Definition and Application Boundaries of Fuel Lines


1. Core Concept Definition

A fuel line is a dedicated fluid transmission path connecting the fuel tank and the engine (or various combustion devices). It mainly undertakes three core functions:?fuel pressurization, impurity filtration, and precise distribution, and is an irreplaceable key carrier in the fuel supply chain of the power system.


2. Application Scenario Classification and Adaptation Requirements

JIATIAN's fuel lines adopt customized structural designs for the differentiated working conditions of different scenarios, and the specific adaptation standards are shown in the table below:

Application Scenario

 Core Working Condition Requirements JIATIAN Product Adaptation Selling Points
Automotive Field High-frequency vehicle vibration, wide temperature range of -40℃~120℃, ultra-low leakage rate Professional anti-vibration structure, O-ring/bellows double sealing, lightweight alloy pipe
Construction Machinery High dust erosion, strong acid-base corrosion, high-pressure impact of 10-35MPa Corrosion-resistant and high-pressure special materials, three-stage progressive filtration system, quick-connect leak-proof joints
Marine/Aviation Long-distance transmission, high sealing performance, high salt spray corrosion environment Compact modular pipeline network, DOT SureLock anti-loosening joints, salt spray corrosion-resistant coating


3. Core Component Composition

JIATIAN's fuel line adopts an integrated modular design, consisting of five core subsystems: low-pressure/high-pressure delivery pipes, multi-stage filters, pressure regulators, customized seals, and multi-specification quick-connect joints. Its integrated structure enables rapid on-site assembly, meeting the core demand for efficient operation and maintenance of industrial equipment.


Key Performance Indicators of Fuel Lines and JIATIAN's Technical Advantages


1. Industry Core Technical Indicators and Product Compliance

The performance of fuel lines directly determines the reliability and fuel economy of the power system. The industry's general core indicators and the specific parameters of JIATIAN's products are shown in the table below:
Technical Indicator Industry General Standard Requirements JIATIAN Product Measured Parameters Core Technical Advantages
Temperature Resistance Range -30℃~100℃ -40℃~150℃ Adopts high-temperature resistant special rubber and metal composite pipes, suitable for extreme temperature difference working conditions
Pressure Resistance Level Regular ≤25MPa Can withstand up to 35MPa High-strength lightweight alloy pipe + optimized pipe diameter design, balancing pressure resistance and lightweight
Filtration Precision Regular ≥10μm Front pre-filtration (50μm) + sedimentation buffer filtration + fine filtration (5μm) Three-stage filtration can remove 99.5% of particles, moisture and paraffin, fully protecting the injection system
Seal Leakage Rate ≤5×10??m3/s ≤1×10??m3/s Double sealing structure of bellows end + special sealing gasket, achieving ultra-high standard sealing
Anti-vibration Level Meets ISO 16750-3 vibration standard 20% better than ISO 16750-3 standard Exclusive anti-vibration and anti-impact structural design, suitable for high-frequency vibration scenarios of construction machinery


2. Core Technical Principles?

  • Multi-stage Filtration Principle: The three-stage filtration system of JIATIAN's fuel line adopts the logic of "progressive impurity interception". Fuel first passes through the front pre-filter to intercept large particles above 50μm, then separates moisture and paraffin through the middle sedimentation buffer filter, and finally filters fine particles below 5μm through the end fine filter to ensure that the cleanliness of the fuel entering the high-pressure injection system meets the standard.
  • Sealing and Leak-proof Principle: The product adopts "double sealing protection". Custom O-rings are equipped at the pipeline joints, and integrated welded sealing gaskets are used at the bellows ends. At the same time, various types of quick-connect joints such as thread, buckle, and DOT SureLock are used, which not only ensure the connection strength, but also fundamentally prevent fuel leakage and impurity intrusion.

JIATIAN can provide matching filter elements and standardized replacement guidance to ensure the continuous effectiveness of the filtration system.
  5. What are the precautions for product transportation and installation?
    During transportation, avoid collision of pipeline joints, and it is recommended to use JIATIAN's customized protective packaging; installation must be operated in accordance with the modular assembly manual, and the quick-connect joint must be confirmed to be locked in place (DOT SureLock joint has a locking prompt). It is strictly forbidden to privately modify the pipeline diameter and connection method, so as not to affect the pressure resistance and sealing performance of the product.
