7.3L HPOP Outlet Fittings

Almost infamous are the high pressure oil pump output fittings where the cylinder head oil feed lines connect on 7.3L Power Stroke engines. The fittings can loosen and the o-rings deteriorate. When this happens it creates a severe oil leak that pools in the engine valley and drains down the back of the engine.
