The Cummins fuel injector (Part Number: 4025299) is primarily used in heavy-duty diesel engines across various industrial and commercial applications.

Below are the specific equipment models and engines where this injector is commonly found:

1. Compatible Cummins Engine Models

The 4025299 injector is typically used in the following Cummins engine families:

ISX15 (2013 and earlier models, pre-EPA 2010)

QSX15 (Industrial & off-highway applications)

Signature 600 (ISX) (Earlier models before emissions updates)

KTA19 (Some older industrial engines)

*(Note: Later ISX models (post-2010) may use different injectors due to emissions upgrades.)*

2. Equipment Applications

This injector is found in a wide range of heavy-duty machinery, including:

A. On-Highway Trucks

Freightliner Cascadia (with Cummins ISX15)

Peterbilt 379/389 (Pre-2010 ISX engines)

Kenworth T800/W900 (Older ISX-powered models)

International ProStar+ (Certain Cummins-equipped variants)

B. Off-Highway & Industrial Equipment

Caterpillar 785 & 789 (Mining trucks with Cummins QSX15)

Komatsu HD785 (Some models with Cummins power)

Terex TR100 (Mining trucks with QSX15)

Volvo Construction Equipment (Certain older models)

C. Power Generation & Marine

Cummins QSX15-G (Generator sets)

Marine propulsion engines (Some older industrial/marine applications)

3. Key Considerations

Emissions Compliance: This injector is often used in pre-2010 engines before stricter EPA Tier 4/DPF requirements.

Cross-Reference: Always verify with Cummins Quickserve or dealer systems, as part numbers may vary by engine serial number.
