Role of Part 4007902 Fuel Plumbing Bracket in Engine Systems

The 4007902 Fuel Plumbing Bracket is an essential component in the arrangement of various engine systems, ensuring the efficient and safe operation of fuel lines within the engine compartment.

In conjunction with the Crankcase Breather System, the Fuel Plumbing Bracket secures fuel lines away from moving parts and high-temperature areas, reducing the risk of fuel line damage and potential leaks. This is particularly important as the crankcase breather releases pressure built up within the crankcase, and the proximity of fuel lines to this system must be carefully managed.

The Breather component of the crankcase system works in tandem with the Fuel Plumbing Bracket to maintain a balanced pressure environment. The bracket ensures that fuel lines do not interfere with the breather’s function, allowing for the efficient release of gases while keeping the fuel system intact and operational.

Overall, the 4007902 Fuel Plumbing Bracket plays a significant role in the structural integrity and functional efficiency of the fuel delivery system within the engine, supporting both the crankcase breather and the broader crankcase system ².

Conclusion

The Fuel Plumbing Bracket 4007902 by Cummins is a critical component in the fuel system of commercial trucks, ensuring the efficient and safe operation of fuel lines. Its robust design, ease of installation, and compatibility with various Cummins engines make it a versatile and reliable choice for maintaining the integrity of the fuel system.
