Trust the Delphi Legacy for Diesel Fuel System Innovation
Delphi has engineered fuel injection systems for over a century. Their injectors are known for:
- High-pressure fuel atomization
- Long-term durability in industrial engines
- Consistent fuel-air mixture control
- Compatibility with both mechanical and electronic systems
From compact engines to construction-grade diesel platforms, Delphi injectors deliver under pressure.
Upgrade Engine Response with the Right Delphi Injector
Not all diesel injectors are created equal. Delphi injectors help correct:
- Misfiring during acceleration
- Cold start issues
- Poor fuel mileage
- Uneven idling and rough noise
- Black or white smoke under load
Replacing worn injectors with Delphi units restores engine efficiency and improves combustion quality.
Get Access to Specialized Delphi Injector Types
We supply:
- Delphi Common Rail Injectors – For high-pressure systems with fast fuel delivery and better throttle response.
- Delphi HEUI Injectors – Designed for CAT 3126 engines, offering solenoid-actuated performance.
- Delphi Mechanical Injectors – For older diesel platforms using Lucas CAV systems.
Each injector comes with precise internal component matching, ensuring minimal variation in output.

FAQs About Delphi Diesel Fuel Injectors
1. Do your Delphi injectors require special calibration?
Most Delphi CR and HEUI models function as plug-and-play. Some units may require calibration through the Electronic Control Unit (ECU); check your engine manual for details.
2. Can I reuse my old injector cups with rebuilt Delphi injectors?
We recommend replacing cups if there's carbon buildup or erosion. New injectors function best with clean fuel delivery paths.
3. How do I know if my Delphi injector is failing?
Watch for rough idle, increased fuel use, and delayed throttle response. We can inspect your unit if needed.
4. Are Delphi injectors better than other brands?
Delphi injectors excel in OEM consistency, precise spray control, and low failure rates—especially in industrial and agricultural engines.
