ABSTRACT:
A high pressure fuel line connection assembly for a fuel injector positioned in a cylinder head of an internal combustion engine is disclosed. The cylinder head includes at least two bores formed therein with the second bore intersecting the first bore at an angle with respect to an axial direction of the first bore. A fuel injector is received in the first bore for injecting fuel into a cylinder of the engine, a fuel line for directing fuel to the fuel injector, an intermediate elongated fuel line adapter are received in the second bore for fluidicly conducting fuel from the fuel line to the fuel injector. The elongated fuel line adapter includes a first end contacting the fuel injector in a region of the fuel injector for receiving fuel to be injected and a fuel line connection fitting for biasing an end of the fuel line against a second end of the adapter and the first end of the adapter against the fuel injector in order to sealingly engage the adapter with both the fuel line and the fuel injector.
