Fuel pump assembly OE LR043385 Electric fuel pump Fuel pump module assembly for Land Rover
Product Description:
Fuel Pump Assembly
OE number: LR043385 LR127415
Applicable vehicle type: For Land Rover
The fuel pump, by continuously drawing and pressurising petrol, ensures the smooth flow of fuel from the tank to the engine, making it an indispensable component within the vehicle's fuel system. Should the fuel pump malfunction, it will directly impact fuel supply, leading to issues such as reduced engine power, unstable idling, or even failure to start.
Over extended periods of operation, petrol pumps may develop various faults that directly compromise the vehicle's fuel delivery, thereby degrading engine performance. Common petrol pump malfunctions include:
- Pump housing wear: Prolonged use may cause internal components such as impellers, blades, or plungers to deteriorate through wear, reducing pumping efficiency and preventing adequate fuel pressure generation.
- Clogged filter screen: Impurities, moisture, or gummy deposits within the fuel tank may gradually obstruct the fuel pump's inlet filter screen, restricting fuel intake and causing insufficient fuel supply. This blockage reduces pumping pressure, resulting in diminished engine power.
- Motor failure: Prolonged operation or excessive current may burn out the petrol pump motor, preventing rotation and rendering the fuel pumping function inoperative. Motor failure typically manifests as the vehicle being unable to start or stalling unexpectedly during operation.
- Seal deterioration: Rubber components within the petrol pump, such as seals and oil seals, may gradually age, harden, or crack due to prolonged exposure to petrol and high temperatures. This leads to compromised sealing, resulting in fuel leakage or vapor lock. Seal failure can cause unstable fuel pressure or even vapor lock, resulting in interrupted engine power.
- Impeller Seizure: The impeller is the core component of the fuel pump. If it becomes jammed by foreign objects or is damaged itself, it cannot rotate normally, causing the pump to lose its fuel delivery function. Impeller seizure is usually caused by excessive impurities in the fuel tank or severe impeller wear.
- Pressure valve failure: Damage to the internal pressure regulator or check valve within the fuel pump can cause abnormal fuel pressure. For instance, a pressure valve that fails to close may result in fuel backflow and insufficient pressure; a faulty check valve may cause fluctuating pump pressure or interrupted fuel supply.
- Sensor malfunction: Modern automotive fuel pumps often incorporate a Fuel Pump Control Module (FPCM) or Fuel Pump Control Sensor to monitor pump operation and fuel pressure. Should these sensors malfunction, the ECU may misinterpret the fuel pump's status, leading to erroneous warnings or control anomalies that adversely affect engine performance.
The aforementioned fault types may occur individually or in combination, necessitating diagnosis and repair based on specific circumstances. In practical operation, regular inspection and maintenance of the fuel pump is essential to prevent these faults from occurring.
