Product Overview
Hard starting, rough running, excessive smoke, a persistent miss or loss of power can be related to an injector that is sticking, leaking or no longer atomizing fuel correctly. Because compression, pump condition and fuel supply can create similar symptoms, injector replacement should follow proper diagnosis.
This replacement injector restores the metered high-pressure fuel delivery at the cylinder when the original injector has been confirmed faulty. Correct injector specification is important for spray pattern, timing and engine operation.
Key Features & Performance
- Services the diesel fuel-injection system
