ABSTRACT:
Provided is a fuel injector remover for removing a fuel injector from a cylinder head wherein the fuel injector is located within a counterbore of the cylinder head. The remover includes a primer mover having a piston defining a central bore. A snout portion is attached to the prime mover and defines a central bore. The snout portion has a first end attached to the prime mover and a second end defining a tapered portion sized such that when the tapered portion abuts an outer diameter of the cylinder head counterbore, the prime mover is centered over the fuel injector. A puller rod extends through the central bores of the piston and the snout. A thumbscrew is provided for attachment to the threaded end of the puller rod after the puller rod has been inserted through the central bore of the cylinder.
