The QSK19 CM850 MCRS engine, while part of the same series, is distinct due to its marine application. However, the compatibility with the Fuel Supply Tube part 4956225 ensures that marine operators can rely on the same high-quality fuel delivery system as their land-based counterparts.

Role of Part 4956225 Fuel Supply Tube in Engine Systems

The Part 4956225 Fuel Supply Tube is an integral component within the fuel system, facilitating the seamless transfer of fuel from the fuel tank to the engine. Its primary function is to ensure a consistent and reliable supply of fuel, which is essential for the engine’s operation.

Integration with the Fuel Pump

The Fuel Supply Tube connects directly to the fuel pump, which is responsible for drawing fuel from the tank. This tube acts as a conduit, allowing the pressurized fuel to travel from the pump to other parts of the fuel system. The efficient design of the tube minimizes fuel loss and ensures that the fuel reaches the engine under the correct pressure.

Contribution to the Fuel System

Within the broader fuel system, the Fuel Supply Tube plays a significant role in maintaining the integrity of the fuel flow. It is designed to withstand the pressures and temperatures associated with fuel transport, ensuring that the fuel remains clean and free from contaminants as it moves through the system. This is vital for the proper functioning of fuel injectors and other components that rely on a consistent fuel supply.

Interaction with Engine Monitoring Systems

Modern engine monitoring systems rely on accurate fuel delivery to optimize performance and efficiency. The Fuel Supply Tube contributes to this by providing a stable fuel flow, which allows the monitoring system to make precise adjustments to fuel delivery based on engine demand. This interaction ensures that the engine operates within optimal parameters, enhancing both performance and fuel economy.

Overall Impact on Engine Performance

The consistent and reliable fuel supply facilitated by the Fuel Supply Tube is fundamental to engine performance. It ensures that the engine receives the necessary fuel at the right pressure and temperature, which is essential for combustion efficiency.
