Each of the fuel injectors (12) is fluidly connected to a gaseous fuel common rail through a quill (30) and an outer passage (49) defined between an inner tube (50) and an outer tube (40). Each of the fuel injectors (12) is fluidly connected to a liquid fuel common rail through the quill (30) and an inner passage (51) defined by the inner tube (50). Each combination of an inner tube (50) and outer tube (40) extend into the engine housing (6) between the quill (30) and one of the fuel injectors (12). Each of the inner tubes (50) extends through one of the outer tubes (40) and is compressed between a conical seat (38) on the quill (30) and a conical seat (38) on one of the fuel injectors (12).",
