Role of Part 3004368 Fuel Supply Tube in Engine Systems

The Part 3004368 Fuel Supply Tube is an integral component in the fuel delivery system of various engine setups. It facilitates the smooth and consistent transfer of fuel from the fuel tank to other essential components within the engine system.

In systems equipped with a Fuel Governor, the Fuel Supply Tube ensures a steady fuel flow, which is vital for the governor to regulate fuel delivery based on engine load and speed. When paired with a Fuel Pump, this tube plays a role in maintaining the pressure required for efficient fuel atomization in the combustion chamber.

For engines utilizing a Fuel Pump and Governor combination, the Fuel Supply Tube is essential in linking these two components, allowing for precise fuel management. In setups with a Fuel Pump Coupling, the tube aids in transferring fuel while accommodating the mechanical connections necessary for the coupling’s operation.

In systems with a Governor Sump or a Hydraulic Governor, the Fuel Supply Tube ensures that fuel is adequately supplied to these components, which in turn regulate engine speed and power output.

The tube also interfaces with the Lubricating Oil Tube Mounting and the Lube Oil Tube, ensuring that fuel and lubrication systems operate harmoniously without cross-contamination.

For engines with a W/W Governor Assembly, the Fuel Supply Tube is crucial for delivering fuel to the governor, which then modulates fuel flow to match engine demands.

In systems utilizing Woodward 2301 Governor, Woodward 2301A Governor, Woodward Governor, Woodward PSG Governor, Woodward SG Governor, and Woodward SG, the Fuel Supply Tube ensures that these sophisticated governors receive a consistent fuel supply, enabling them to perform their speed and load regulation functions effectively.

Overall, the Part 3004368 Fuel Supply Tube is a key element in ensuring the reliable and efficient operation of various engine components, contributing to the overall performance and durability of the engine system.

Conclusion

The Cummins 3004368 Fuel Supply Tube is a critical component in the fuel delivery system of heavy-duty trucks. Its role in ensuring a consistent and reliable fuel supply is essential for maintaining engine performance and efficiency. With its durable construction, precise engineering, and compatibility with various engine models, this Cummins part contributes significantly to the reliability and durability of the engine system.
