You are bidding on a Kent Moore Injector Seals Installer Sizer Tool Set EN-49245. This tool set is in overall very good condition. Same some $ here and thanks for looking! Info Applications: LF1 3.0L The Hitachi SIDI system used on some LF1 3.6L V6 and LAF 2.0L ECOTEC has 2 seals in the injector tip. These seals must be installed into their grooves, and then sized to the engineered dimension before the injectors are installed into their bores in the cylinder head. There are two seal installation pilots included in EN-49245 (one for each groove) which allow the seal to slide onto the injector tip without catching on any machined surface, or the incorrect groove.
