Part 3010761 Fuel Supply Tube Component Usage

The 3010761 is an essential component in the fuel delivery system of various engine setups. It is responsible for transporting fuel from the fuel tank to the engine’s fuel injection system or carburetor. Here’s how it integrates with other components:

• Actuator Plumbing: The Fuel Supply Tube interfaces with the actuator plumbing to ensure precise fuel delivery. This connection is vital for maintaining the correct fuel pressure and flow rate, which are necessary for optimal engine performance.

• Fuel Tubing: The Fuel Supply Tube is often connected to other sections of fuel tubing. This setup creates a continuous pathway for fuel to travel from the tank to the engine. Proper sealing and connection between these tubes are important to prevent fuel leaks and ensure consistent fuel pressure.

• MTG (Mechanical Timing Governor): In systems equipped with an MTG, the Fuel Supply Tube provides the necessary fuel to the governor. This allows the MTG to regulate fuel flow based on engine timing, contributing to efficient combustion and reduced emissions.

• American Bosch Gov. (Governor): Similar to the MTG, the American Bosch Governor relies on a steady supply of fuel from the Fuel Supply Tube. This ensures that the governor can accurately control fuel delivery in response to engine load and speed variations.

• MTG. (Mechanical Timing Governor): When present, the MTG. uses the Fuel Supply Tube to receive fuel. This connection is essential for the governor to modulate fuel injection timing, which is key to maximizing engine efficiency and performance.

• Fuel Supply: The primary role of the Fuel Supply Tube is to act as a conduit within the fuel supply system. It ensures that fuel is delivered efficiently and under the right conditions to the engine’s fuel injection system or carburetor, supporting smooth and reliable engine operation.

Conclusion

The Cummins 3010761 Fuel Supply Tube is a critical component in the fuel delivery system of commercial trucks, ensuring a consistent and reliable fuel supply to the engine. Its durable construction, compatibility with Cummins engines, and role in maintaining engine performance and efficiency make it an essential part for technicians and engineers working with Cummins engines.
