    摘要: An internal combustion engine includes an engine block defining at least one row of cylinders extending from a first end toward a second end. A flywheel housing is attached to the first end of the engine block and includes a pump engagement face having a first pump lubrication supply port opening therethrough. A high pressure fuel pump includes a flywheel housing engagement face having a second pump lubrication supply port opening therethrough. The pump engagement face of the flywheel housing abuts the flywheel housing engagement face of the high pressure fuel pump such that the first pump lubrication supply port and the second pump lubrication supply port are in fluid communication.
