The Fuel Supply System of the FAW truck is a complex and crucial system that consists of various components working together to ensure the efficient delivery of fuel to the engine. At the heart of this system is the 1111010-775 (1111500-M81-1A52B)(1111500-M81-1A52BW) Fuel injection pump assembly, which is responsible for precisely metering and delivering the correct amount of fuel to the engine cylinders. This component is essential for the proper functioning of the engine and plays a key role in the overall performance of the vehicle.

In addition to the fuel injection pump assembly, the system also includes the 1111228-775 (1111228-M80-0000) Adapting flange, injection pump, which ensures a secure and proper connection between the injection pump and the engine. This component is crucial for maintaining the integrity of the fuel supply system and preventing any leaks or malfunctions that could compromise the performance of the vehicle.

To further enhance the reliability of the system, components like the CQ73431550C Hydro-pneumatic rubber O-ring and the (GB/T3452.1155X2.65) O-ring rubber seal 155X2.65 are utilized to create a tight and secure seal. These rubber seals play a vital role in preventing fuel leakage and ensuring that the system operates smoothly and efficiently.

In terms of assembly, the system incorporates components such as the Q1841040 Hexagon head flange bolt, Q1841030 Hexagon head flange bolt, CQ1201035 Stud bolt, CQ39610 (Q32010) Hexagon nut with flange, and Q18210100 Hexagon flange bolt with fit neck. These bolts, nuts, and studs are designed to securely fasten the various components of the fuel supply system together, ensuring stability and preventing any loosening or detachment during operation.

Overall, the Fuel Supply System of the FAW truck is a well-engineered and meticulously designed system that incorporates high-quality components to deliver optimal performance, efficiency, and reliability. By combining precision-engineered components with robust construction, the system ensures a steady and consistent supply of fuel to the engine, ultimately contributing to the overall performance and longevity of the vehicle.
