Abstract
A carrier for mounting to an internal combustion engine having an intake manifold port, a fuel injector and a cylinder head port extending from a cylinder head. The carrier includes a central portion having an internal passageway for providing fuel to the fuel injector. An attachment portion extends from the central portion which is affixed between the cylinder head and the intake manifold ports. The carrier further includes a sleeve extending from the central portion for receiving the fuel injector, which is sealed by the sleeve and an O-ring. The fuel injector, port seals, injector O-ring, wiring harness, connector and fuel rail are integrated into a single carrier to provide sealing, electrical connectivity, and fuel delivery functions.
