Cummins Service Products Catalog – Tool 3163194Injector Fuel Shut-Off

SMALL | MEDIUM | LARGE

Engine Family: QSKV 45/60

This tool is used in the diagnosis of a malfunctioning injector by shutting off the fuel supply to the injectors one by one. After a good injector is disabled by this process, there will be a distinctive drop in engine idle speed. Disabling a bad injector will cause no change in engine idle speed.
