Compatibility with Cummins Engines

The Fuel Supply Tube (part number 3082466) is specifically designed to fit the following Cummins engines:

• N14 Celect Plus

This part is integral to maintaining the performance and reliability of the N14 Celect Plus engine, ensuring that the fuel supply remains uninterrupted and consistent, which is crucial for the engine’s operation ².

Installation and Functionality

When installed in the N14 Celect Plus engine, the Fuel Supply Tube connects the fuel tank to the fuel injection pump, facilitating the movement of fuel. It is essential to use the correct part number to ensure compatibility and proper function. The tube is typically made from durable materials to withstand the pressures and conditions within the engine’s fuel system ².

Importance of the Fuel Supply Tube

The Fuel Supply Tube plays a vital role in the overall functionality of the engine. A malfunctioning or damaged tube can lead to fuel delivery issues, which may result in engine performance problems or even engine failure. Regular inspection and maintenance of this component are recommended to prevent potential issues ².

Maintenance Tips

To ensure the longevity and proper function of the Fuel Supply Tube, it is advisable to:

• Regularly inspect the tube for signs of wear, cracks, or leaks.
• Ensure that all connections are secure and free from corrosion.
• Replace the tube if any damage is detected to avoid fuel delivery problems ².

Integration with Fuel Tank and Pump

The Fuel Supply Tube connects directly to the fuel pump, which is housed within the fuel tank. This connection is vital for drawing fuel from the tank and initiating its journey towards the engine. The tube is designed to withstand the pressure exerted by the fuel pump, maintaining the integrity of the fuel line ².

Pathway to the Fuel Filter

Following its connection to the fuel pump, the Fuel Supply Tube routes the fuel to the fuel filter. The filter’s role is to remove impurities and contaminants from the fuel, ensuring that only clean fuel reaches the engine. The tube’s durable construction prevents leaks and maintains a secure connection between these components ².

Connection to the Fuel Rail or Carburetor

In fuel-injected engines, the Fuel Supply Tube delivers fuel to the fuel rail, which distributes it to individual injectors. Each injector meters the precise amount of fuel required for combustion, optimizing engine performance and efficiency. In carbureted engines, the tube directs fuel to the carburetor, where it is mixed with air before entering the combustion chamber ².

Role in Fuel Return Systems

In systems equipped with a fuel return line, excess fuel not used by the engine is returned to the tank. The Fuel Supply Tube plays a part in this process by ensuring that the fuel system remains pressurized, facilitating efficient fuel delivery and return ².

Compatibility with Fuel Regulators

The Fuel Supply Tube also interfaces with the fuel pressure regulator, which maintains consistent fuel pressure within the system. This regulator helps to ensure that the engine receives the correct fuel pressure under varying operating conditions, contributing to stable engine performance ².

Conclusion

The Cummins 3082466 Fuel Supply Tube is a critical component in the fuel delivery system of commercial trucks, ensuring efficient and reliable transfer of fuel from the tank to the engine. Its robust design, compatibility with specific Cummins engines, and integration within the fuel plumbing system highlight its importance in maintaining engine performance and efficiency. Regular maintenance and inspection are essential to prevent issues and ensure the longevity of this component.
