Cummins 6BT Engine Injectors & Fuel System Components

The Cummins 6BT is trusted worldwide for its rugged performance and longevity in both marine and industrial applications. At the core of its fuel system are the diesel injectors — precision-engineered components that deliver the exact amount of fuel at the correct timing for optimal combustion.

Worn or faulty injectors can lead to poor performance, increased fuel consumption, excess smoke, and costly engine damage. Replacing injectors with the correct CPL-matched components ensures your 6BT continues to perform at peak efficiency.

Injector Kit for CPL 1975 & 2205

This injector kit is designed specifically for Cummins 6B and 6BT engines configured with CPL numbers 1975 and 2205. It is manufactured to OEM specifications for precise fuel atomization and consistent spray patterns, ensuring smooth operation and optimal combustion efficiency.

Ideal for both marine and industrial engines, this kit comes complete with the injector body, nozzle, seals, and washers for an all-in-one installation solution.

Injector Kit for CPL 2208 & 8457

Engines with CPL 2208 or 8457 require this injector configuration to maintain correct fuel delivery and timing. The kit provides matched flow rates across all cylinders to minimize imbalance, reduce emissions, and maintain consistent horsepower output.

Built with corrosion-resistant materials, this kit is well-suited for marine conditions and extended duty cycles.

Injector Kit for CPL 594, 696, 710, 730, 938, 1277, 1278, 1279, 1288, 1289, 1520, 1525, 2021

This injector kit covers a wide range of CPL configurations found in both early and later Cummins 6BT engines. It is engineered for engines that require precise fuel metering to ensure stable idle, responsive acceleration, and optimal fuel economy.

Each injector undergoes rigorous testing for spray pattern and opening pressure to guarantee performance consistency.

Injector Kit for CPL 742, 953, 1685

Designed for 6BT engines with CPL numbers 742, 953, and 1685, this injector kit ensures proper fuel delivery characteristics tailored to these configurations. The precise spray pattern reduces carbon buildup, helping to extend engine life and maintain fuel efficiency.

Injector Kit for CPL 2208 (Alternate Specification)

This is an alternate-specification injector for certain CPL 2208 engine builds. While similar to the standard version, it features calibration differences suited for specific operational requirements. It is essential to verify your exact CPL and engine configuration before selection.

Injector Kit for CPL 1928

The CPL 1928 injector kit is engineered for exact fit and performance in its designated engine setup. Its robust design ensures reliable operation even in continuous-duty marine environments where fuel system stability is critical.

Injector Kit for CPL 2968

This injector kit is designed for CPL 2968 Cummins 6BT engines, delivering optimal combustion performance with precise fuel spray and flow control. Its rugged construction provides durability under high-load, high-hour conditions.

Fuel Manifold for 4B and 4BT Engines

Although specifically listed for the 4B and 4BT series, the fuel manifold is a vital part of the Cummins B-series fuel system architecture. It evenly distributes fuel from the injection pump to the injectors, ensuring consistent delivery across all cylinders. Replacing the manifold during injector service is recommended to maintain system balance and performance.

Banjo Connector Seal

The banjo connector seal is a small but essential part of the high-pressure fuel system. Each injector requires one of these seals to prevent leaks at the fuel inlet. Replacing these seals whenever injectors are serviced ensures maximum efficiency and prevents fuel system air intrusion.

Why CPL Matching Matters for Cummins 6BT Injectors

Each CPL number represents a specific combination of pistons, timing, fuel mapping, and other variables. Using injectors that are not CPL-matched can lead to:

• Over-fueling or under-fueling

• Reduced performance and efficiency

• Excessive smoke or emissions

• Potential piston and cylinder damage

By selecting CPL-matched injectors, you maintain the performance profile and reliability the 6BT is known for.
