Diesel Engine Fuel Pump 294050-0204 Featuring a simple and practical modular design, the pump body is lightweight, weighing only 3.6kg, reducing engine compartment load. Internal core components are made of high-quality alloy materials, precision-machined and rigorously tested to ensure they meet the demands of daily use. The pump's fuel supply system is simple and efficient, with low pressure loss, maintaining stable fuel pressure at different speeds to ensure smooth engine idling and rapid acceleration response. Its seals are made of high-quality oil-resistant and high-temperature-resistant rubber, combined with a semi-sealed pump body structure, effectively preventing fuel leakage and impurity intrusion, while also maintaining low operating noise and improving driving comfort. In terms of fuel compatibility, it is compatible with standard diesel and E10 biodiesel, and with a 150μm filtration precision pre-filter, its service life is effectively extended. Furthermore, this model is extremely easy to install; the standardized interface is fully compatible with the installation locations of most passenger cars and light trucks, requiring no complex modifications, and even users with basic maintenance experience can replace it themselves.

FAQ
Q: What are the main performance differences between this fuel pump and the higher-end models in the same series?
A: The core difference lies in its performance under extreme conditions. This model is perfectly adequate for daily commuting and short-distance transportation, while the higher-end models excel in high-load continuous operation and extreme temperature adaptability, and are also relatively more expensive.
Q: Is a sudden increase in fuel consumption during daily use related to the fuel pump?
A: This could be due to abnormal fuel pump supply pressure or decreased injection accuracy. We recommend first checking if the fuel filter is clogged. If cleaning does not improve the situation, the fuel pump's operating pressure can be tested with professional equipment, and repair or replacement may be necessary.
Q: What precautions should be taken when installing this fuel pump yourself?
A: Before installation, disconnect the power supply and ensure there is no pressure in the fuel line; during installation, ensure the interfaces are properly sealed and the tightening torque meets standards; after installation, purge the air from the lines before starting the engine to avoid dry running and wear on the internal pump components.
