Why Matching Matters

Consistency Starts with Verification

Uneven fueling can contribute to driveability, fuel-use and durability issues. The correct diagnosis depends on the engine, injector condition and application.

For each quoted Dominator set, confirm the rebuild scope, test process, matching method, trim-file availability and fitment inputs in writing before ordering.

What to Confirm

Four Parts of a Documented Rebuild

The applicable process and included components vary by injector. Your written quote should identify the details for the selected part number.

01

Component Review

Gaskets, springs, O-rings, nozzle, valve, body and solenoid are evaluated against the applicable build criteria; replacement and service scope vary by SKU.

Confirm the included component and service scope.
02

Traceable Process

Applicable units can be serialized to available build and test records. Ask which traceability details and records are supplied for your SKU.

Traceability details vary by part number.
03

Calibration and Matching

Bench testing, calibration and set matching are applied as specified for the application. Trim-file availability varies by engine and injector.

Confirm the matching method and supplied trim files.
04

Quality Assurance

Mechanical and electronic checks are completed against the applicable build specification. Ask for the test scope and acceptance criteria.

Test details are available for the selected part number.

Treated As An Electromechanical Part

Inspected Two Ways, Mechanical & Electronic

An EUI combines mechanical and electronic systems. The applicable rebuild scope should address both, with the included work documented for the selected part number.

Teardown and inspection — components are serviced or replaced as specified for the selected SKU.
Solenoid evaluation — electronic checks and replacement requirements vary by unit.
Nozzle inspection — service steps are applied against the applicable build criteria.
Documentation and warranty — confirm test criteria, coverage and exclusions before ordering.
