Product introduction
As a core pre-component of the Cummins ISX fuel pump system, the G5338665 ensures continuous and reliable operation of heavy-duty diesel engines under harsh conditions due to its high durability and anti-pollution capabilities. The 2004 Cummins injectors are specifically matched to the ISX 6.7L 2004 engine and feature a built-in pulsation damping chamber structure, controlling fuel supply fluctuations within ±0.2 bar, ensuring stable pressure in the HEUI hydraulic drive system and an injection response delay of less than 1.5ms.

Product Advantages
The Cummins G5338665 fuel pump is specifically optimized for HEUI systems, featuring a high-strength aluminum alloy housing and an embedded multi-layer precision filter with a filtration accuracy of 5μm. This effectively blocks fuel impurities, prevents wear on the high-pressure pump plunger and injector solenoid valve, and significantly extends system life. The Cummins N14 fuel pump, as standard equipment on the N14 engine's HEUI system, features a hydrodynamic design that achieves a continuous flow output of 120 L/h. Combined with the P7/P8 high-pressure pump, it forms a closed loop of "low-pressure pre-compression-high-pressure boost," ensuring a continuous and stable injection pressure above 1200 bar, and improving power output linearity by 18%.
FAQ
Q: 1.Which engines is the Cummins G5338665 fuel pump specifically designed for?
A:The G5338665 is an original equipment manufacturer (OEM) low-pressure booster pump designed specifically for Cummins N14 and ISX 6.7L engines, particularly compatible with the 2004 HEUI system. It provides stable fuel pre-pressure to the high-pressure injectors, ensuring injection accuracy and system reliability.
Q: 2.What is the difference between the Cummins 6.7 booster pump and a regular fuel pump?
A:The Cummins 6.7 booster pump is optimized for the ISX 6.7L engine, featuring wide-temperature-range start-up capability and a pulsation damping structure. It can control fuel supply fluctuations within ±0.2 bar, significantly improving the response speed and stability of the HEUI system.
Q: 3. What are the core advantages of the Cummins ISX fuel pump system?
A:The Cummins ISX fuel pump system, starting with G5338665, constructs a closed loop of "low-pressure pre-compression-high-pressure boost-precision injection," achieving a filtration accuracy of 5μm throughout the system and a maintenance cycle of up to 10,000 hours. It is a recognized reliability benchmark in the heavy-duty truck and construction machinery industry.
Q: 4. Can the Cummins N14 fuel pump be air-freighted?
A:What precautions should be taken? It can be air-freighted, but the internal fuel must be emptied and a dangerous goods label affixed. An MSDS and original manufacturer's certificate of no fuel should also be provided. It is recommended to use original manufacturer's sealed packaging to prevent internal parts from shifting due to transportation vibrations.
Q: 5. How to ensure smooth customs clearance when shipping the Cummins ISX fuel pump and 04 Cummins injectors together?
A:Original manufacturer's invoice, packing list, certificate of origin (CO), and EPA Tier 3 emission compliance documents are required. The pump must be clearly labeled "HEUI fuel system component" to avoid being misclassified as a complete engine. It is recommended to entrust a professional customs broker to handle this.
