Compatibility with Cummins Engines

N14 Mechanical Engines

For the N14 Mechanical engines, the 3006995 is engineered to withstand high pressures and demands, providing a reliable conduit for fuel from the fuel tank to the injection pump. This ensures that the engine receives a consistent and uninterrupted fuel supply, which is essential for maintaining optimal performance and efficiency.

NH/NT 855 Engines

Similarly, the NH/NT 855 engines benefit from the use of the 3006995. This part is designed to integrate smoothly with the fuel systems of these engines, ensuring that fuel is delivered precisely where it is needed. The design of the Fuel Supply Tube is such that it can handle the specific requirements of the NH/NT 855 engines, contributing to the overall reliability and performance of the engine.

By using the 3006995 in both the N14 Mechanical and NH/NT 855 engines, users can be assured of a part that is both durable and effective. This compatibility ensures that the engines can operate at their best, with minimal risk of fuel delivery issues.

Role in Engine Systems

The 3006995 is an essential component in the fuel delivery system of various engine setups. Its primary function is to transport fuel from the fuel tank to the engine’s fuel injection system or carburetor. This ensures a consistent and reliable fuel supply, which is fundamental for the engine’s performance and efficiency.

Integration with Fuel Tubing

The Fuel Supply Tube interfaces directly with the fuel tubing, forming a continuous pathway for fuel. This connection is typically secured using clamps or connectors to ensure a leak-free seal. The tubing itself may vary in material and diameter depending on the engine’s requirements, but the Fuel Supply Tube must be compatible to maintain the integrity of the fuel line.

Mounting Considerations

Proper mounting of the Fuel Supply Tube is vital for its function and durability. The tube is often secured to the vehicle’s chassis or engine bay using brackets or clips. This mounting not only protects the tube from physical damage but also helps manage the fuel line’s routing to avoid interference with other components. The mounting points must be chosen carefully to withstand vibrations and maintain a stable fuel flow.

Functionality

Once mounted and connected to the fuel tubing, the Fuel Supply Tube plays a pivotal role in delivering fuel under pressure to the engine. It must be designed to handle the specific pressure and flow rates required by the engine system. The tube’s material and construction are chosen to resist fuel corrosion and maintain structural integrity under varying temperatures and pressures.

Conclusion

The 3006995 Fuel Supply Tube is a key element in the fuel delivery system, ensuring that fuel is efficiently and reliably transported from the tank to the engine. Its integration with fuel tubing and secure mounting are essential for the overall performance and reliability of the engine system.
