Abstract

Abstract The invention comprises a tool for removing fuel injectors from diesel engines without damaging any adjacent component parts or user's hands. The invention comprises an elongated member having a U-shaped injector engaging member at one end. The elongated member has a locating pin which is adapted to fit inside one of several bolt holes along side a fuel injector in a diesel engine. The locating pin serves as a pivot for the mechanic to manually lever the injector loose from the diesel engine.
