The SP Tools Cummins Common Rail Injector Puller, No. 17200, is designed to remove diesel injectors from Dodge Cummins ISBE HPCR 5.9L and 6.7L engines produced from 2003 to current model year, which are equipped with the high-pressure common rail fuel system. The 17200 enables the technician to quickly and efficiently remove diesel injectors that have become heavily coated over time with carbon between the tip and head. Simply remove the wires and retaining bolts, then slip the puller cup in the groove on the injector, and lever it out.
