The CAT C4.4 Fuel Injectors (part numbers including 3707287, 370-7280, 0330-295050, 0331-3707280) are built for smaller Caterpillar engines, typically used in compact excavators or small power units. These injectors support high-pressure common-rail or electronic injection systems depending on the setup, delivering finely metered fuel for efficient atomization. Their more compact design makes them ideal for tighter engine compartments, yet they still deliver robust performance for their size. When installed correctly, they help reduce smoke, improve fuel efficiency, and maintain consistent engine output under varying loads.
Key Features:
-
Multiple part variants: 3707287, 370-7280, 0330-295050, 0331-3707280
-
Compatible with CAT C4.4 engines
-
Precisely engineered for small but powerful diesel machines
-
Built to handle common-rail pressures (if CR version) or electronic injection
-
Good for maintenance or performance restoration in compact machines
Practical Advice:
-
When replacing these, make sure to verify the correct part variant — there are reman and OEM versions.
-
Because these engines might run in compact or tight equipment, check for heat exposure and ensure injectors are cooled / shielded properly.
-
Regular fuel filter maintenance is crucial — small engines expose injectors to more contaminants.
