The Schley/SP Tools Duramax LB7 Injector Puller Kit, No. 11700, has been designed to remove the diesel injectors from GM vehicles produced from 2001 to 2004 with an LB7 Duramax engine. The 11700 will pull the injector straight out of the full length of the nozzle tip without rocking, which reduces the possibility of unwanted sleeve removal. If a sleeve does come out, the forked tool is used to gently remove the sleeve from the injector without damage so it can be reused.
