HOWO 375 Truck Auxiliary Electric Fuel Pump (HEP-02A Type)

This is an Auxiliary Electric Fuel Pump, often identified by the part number type HEP-02A, suitable for various fuel system applications in HOWO 375 Heavy Duty Trucks. While not typically the primary high-pressure injection pump for a diesel engine, this type of compact, cylindrical electric fuel pump is commonly used as a lift pump, transfer pump, or a universal replacement in various fuel delivery systems. It is responsible for drawing fuel from the tank and delivering it under low pressure to a main fuel pump or filter system.

Key Features:

• Universal/Auxiliary Application: Designed for general fuel transfer duties within heavy-duty diesel fuel systems, such as priming the system, acting as a lift pump, or serving as an in-line booster pump.
• Electric Operation: Provides consistent fuel flow driven by an electrical current (indicated by red and black wires), ensuring reliable fuel delivery.
• Compact Design: Small, cylindrical form factor with clear “IN” and “OUT” ports for easy integration into existing fuel lines.
• Durable Construction: Typically made with a robust metal casing (as seen in the image) to withstand the demands of the truck environment and resist corrosion.
• Basic Mounting: Includes simple mounting bracket for straightforward installation.

Benefits of an Auxiliary Electric Fuel Pump:

• Ensures Consistent Fuel Supply: Helps maintain a steady flow of fuel to the main injection system, vital for engine performance.
• Aids in Priming: Can assist in priming the fuel system after maintenance or running out of fuel, especially in diesel applications.
• Reliable Performance: Provides a dependable means of fuel transfer, reducing the risk of fuel starvation issues.
• Cost-Effective Replacement: Often a more economical solution for auxiliary fuel transfer needs compared to more complex primary pumps.

Please Note: Ensure this pump’s pressure and flow specifications match the requirements of your specific application within the HOWO 375 truck’s fuel system. It is not designed to replace the main high-pressure fuel injection pump found in modern diesel engines. Professional installation is recommended to ensure proper wiring, fuel line connections, and overall system integrity.
