An electromagnetic fuel injector has a tubular non-magnetic body defined by radially inner and outer side walls bounding an annular shaped interior which contains a tubular solenoid coil and an annular valve element that is operated by said solenoid coil to open and close the fuel injector. The radially inner wall bounds a central through-hole in the body that allows the stem of an engine intake valve to pass through the fuel injector, thereby enabling the fuel injector to be mounted on the manifold directly over the valve head. |
