Product Description:

Fuel injector leak off pipe assembly
OE number: LR032107 LR051528
Applicable vehicle type: For Land Rover

A fuel line refers to the piping system used to transport gasoline, typically made of rubber, plastic, or metal. It connects various components of the fuel supply system, including the fuel tank, fuel pump, fuel filter, and fuel injectors. The fuel line delivers fuel from the tank to the engine's fuel injection system, ensuring fuel reaches the combustion chamber safely and reliably.

Over time, fuel lines may develop various faults that directly disrupt the fuel system's functionality. Common fuel line issues and their causes are outlined below:

• Fuel Leakage: This is one of the most frequent fuel line failures. Leaks typically manifest as seepage at pipe connections or cracks/holes in the tubing itself. Causes include: pipe aging or material fatigue (rubber hoses harden and crack over time; nylon hoses may develop cracks due to material degradation); loose connections or damaged seals (e.g., loose clamps, aged gaskets); improper installation or deformation/rupture from external pressure/impact. Fuel leaks not only waste fuel but also pose fire hazards and require immediate repair.
• Blockage: Fuel line blockages obstruct normal fuel flow, causing insufficient engine fuel supply. Blockages may result from fuel contaminants (such as gum or rust) accumulating and gradually clogging the lines, or from a long-unreplaced fuel filter whose clogged element prevents fuel passage, ultimately blocking the line's end. Blockages may also result from debris generated by internal pipe corrosion. Such failures cause reduced engine power and sluggish acceleration, potentially leading to engine stalling in severe cases.
• Wear and Corrosion: Fuel lines endure prolonged fuel immersion and exposure to various engine compartment conditions during operation. Metal fuel lines may corrode due to moisture or corrosive substances in the fuel, developing rust spots or holes. Rubber hoses may accelerate aging and hardening from prolonged exposure to high temperatures and UV radiation, eventually rupturing. Additionally, prolonged friction against other components (such as engine mounts or exhaust pipes) can cause wear, thinning, or even perforation. Wear and corrosion weaken the lines' integrity, increasing the risk of leaks.
• Insufficient Pressure: Low fuel line pressure typically stems not from physical damage to the line itself, but from insufficient fuel supply caused by other component failures. For instance, a malfunctioning fuel pump, clogged fuel filter, or leaking injector can all reduce fuel pressure, resulting in inadequate fuel delivery through the lines. However, from a fuel line perspective, leaks or blockages within the line can also cause actual fuel pressure to fall below normal levels. Insufficient pressure can cause reduced engine power, unstable idle, or even prevent starting.
• Aging Failure: All fuel line materials degrade over time. Rubber and plastic lines exhibit reduced elasticity, hardening, brittleness, and increased susceptibility to cracking. while metal fuel lines may exhibit internal corrosion or surface oxidation. Generally, rubber fuel lines have a relatively short lifespan, typically requiring replacement every 5-10 years or approximately 100,000 kilometers under normal use. Nylon and metal lines offer longer service life. If aged and failed fuel lines are not replaced promptly, a rupture during operation could cause severe fuel leakage and safety incidents.
