The Cummins part 3102752, known as the Fuel Supply Tube, is a critical component in the fuel delivery system of certain Cummins engines. This part is integral to ensuring the efficient and reliable operation of the engines by facilitating the transfer of fuel from the fuel tank to the engine’s fuel injection system.

ISM CM570/870 and ISM CM876 Engines

The ISM CM570/870 and ISM CM876 engines are part of Cummins’ Industrial Series Medium (ISM) lineup, which is designed for heavy-duty applications. The Fuel Supply Tube (part 3102752) in these engines is engineered to withstand the high pressures and demanding conditions typical of industrial and commercial use. This part ensures that fuel is delivered consistently and accurately, which is crucial for maintaining engine performance and longevity ¹⁰.

QSM11 CM876 Engine

The QSM11 CM876 engine, another member of the Cummins lineup, also utilizes the Fuel Supply Tube (part 3102752). This engine is designed for medium-duty applications, providing a balance between power and efficiency. The Fuel Supply Tube in the QSM11 CM876 engine is designed to meet the specific requirements of this engine model, ensuring optimal fuel flow and system integrity ¹¹.

Compatibility and Importance

The Fuel Supply Tube (part 3102752) is a standardized component across these engine models, which simplifies maintenance and repair processes. Technicians and operators can rely on this part to perform consistently across different engine configurations, facilitating easier troubleshooting and part replacement. Ensuring the integrity and proper installation of this component is essential for the overall health and performance of the engine ¹².

Role of Part 3102752 Fuel Supply Tube in Fuel Plumbing Systems

The Part 3102752 Fuel Supply Tube is an integral component in the fuel plumbing system of various engine setups. It serves as a conduit for the delivery of fuel from the fuel tank to the engine’s fuel injection system or carburetor. This tube is designed to withstand the pressures and temperatures associated with fuel transport, ensuring a reliable and consistent fuel supply ¹³.

In fuel injection systems, the Fuel Supply Tube connects to the fuel rail, which distributes fuel to each injector. The tube must be securely fitted to prevent leaks and ensure that the fuel pressure remains consistent, which is essential for the injectors to operate correctly. The tube’s design often includes features such as reinforced ends or barb fittings to ensure a tight seal with the fuel rail and other components ¹⁴.

For carburetor-equipped engines, the Fuel Supply Tube typically connects to the carburetor’s fuel inlet. It may also be linked to a fuel filter, which is positioned inline to trap impurities before they reach the carburetor. The tube’s role is to provide a steady flow of clean fuel, which is vital for the carburetor’s venturi to function properly and mix fuel with air in the correct ratio ¹⁵.

In both systems, the Fuel Supply Tube may also connect to a fuel pressure regulator, which maintains the desired fuel pressure within the system. This regulator can be located either before or after the fuel rail or carburetor, depending on the engine’s design ¹⁶.

The Fuel Supply Tube is also part of a larger network that includes fuel return lines, which carry excess fuel back to the tank. This return system helps to manage fuel temperature and pressure, contributing to the overall efficiency and performance of the engine ¹⁷.

In summary, the Part 3102752 Fuel Supply Tube is a key element in the fuel delivery process, interfacing with various components such as the fuel tank, fuel filter, fuel rail, carburetor, and fuel pressure regulator to ensure that the engine receives the precise amount of fuel it requires for optimal operation ¹⁸.
