Overview
Service Overview
NW Fuel Injection Services tests mechanical and electronic integrated diesel fuel injection systems, including HEUI injectors and electronic unit injectors. For unit injector testing, our Surrey shop uses Hartridge AVM2PC and HI2000 HEUI injector test stands to evaluate high pressure oil actuated injectors and heavy duty EUI applications with controlled RPM, pulse width, control pressure, temperature monitoring, and stiction testing.
HEUI Testing
HI2000 HEUI Injector Test Stand
The HI2000 HEUI injector test stand was custom built in Canada and first introduced in the spring of 2000. It was developed to meet the industry standard for testing Ford 7.3 Powerstroke and Navistar DT466E injectors. NW Fuel has upgraded this bench so it can test nearly every high pressure oil actuated injector in operation today.
- Ford 7.3 Powerstroke HEUI injector testing
- Ford 6.0 Powerstroke HEUI injector testing
- Navistar DT466E, DT530E, T444E, and Maxxforce coverage
- Navistar HEUI and G2.9 injector testing
- CAT 3126 HEUI injector testing
Bench Capabilities
Advanced HEUI Test Parameters
HEUI injectors rely on high pressure oil actuation, so accurate testing needs more than a simple flow check. Our bench can control and monitor operating conditions that directly affect injector performance, including stroke count, temperature, RPM, pulse width, and control pressure. This helps diagnose issues such as stiction, poppet valve leakage, and inconsistent fuel delivery.
- Selectable stroke counter
- Digital temperature monitoring
- Upper and lower poppet valve seat testing
- Specialty engineered stiction testing
- Adjustable RPM, pulse width, and control pressure
EUI Service
Electronic Unit Injector Testing
NW Fuel also tests and services many electronic unit injectors used in heavy duty diesel engines. This includes CAT, Cummins, Detroit, and Volvo injectors. Fast moving injectors may be available from stock, and customer injectors can be tested and repaired in a timely manner based on the application and parts availability.
- CAT electronic unit injectors
- Cummins electronic unit injectors
- Detroit electronic unit injectors
- Volvo electronic unit injectors
- Fast moving injector stock and timely repair options
Service Fit
Injectors We Service
Poppet Valve Testing
Upper and lower poppet valve seat testing helps diagnose internal sealing issues that affect fuel delivery and injector control.

Process
Our Service Process
System Identification
Injector type, engine application, and required HEUI or EUI test parameters are confirmed before testing.
Pre-Test Diagnostics
The injector is tested for stroke, RPM, pulse width, control pressure, temperature behavior, poppet valve sealing, and stiction where applicable.
Service or Rebuild
Results are reviewed to determine whether the injector can be serviced, should be repaired, or needs replacement.
Calibrated Return
Post service verification confirms injector operation at the correct RPM, pulse width, control pressure, and test conditions.
FAQ
Service Questions
Yes. Our HI2000 HEUI test stand has been upgraded to test 6.0 Powerstroke injectors along with Ford 7.3 Powerstroke, Navistar HEUI, G2.9, and CAT 3126 applications.
We test HEUI injectors for Ford 7.3 Powerstroke, Ford 6.0 Powerstroke, Navistar T444E, DT466E, DT530E, Maxxforce, Navistar G2.9, and CAT 3126 engines.
We test and service many electronic unit injectors, including common CAT, Cummins, Detroit, and Volvo heavy duty diesel applications.
The HI2000 can test selectable stroke count, digital temperature behavior, upper and lower poppet valve seat sealing, stiction, RPM, pulse width, and control pressure.
Fast moving injectors may be available from stock. If an injector is not in stock, we can often test and repair your injector based on condition, application, and parts availability.
