Abstract
A cylinder head and high pressure mechanical fuel pump drive for an overhead cam shaft internal combustion engine. The cylinder head in the area of one of its cam shafts is formed with an extending ledge to which a fuel pump mounting member is affixed. This ledge and the mounting member are formed with a bore that receives a cylindrical portion of the housing of the fuel pump and which portion journals the pump driveshaft. A simple O-ring seal seals the pump mechanism in this area from the cam shaft chamber and facilitates a driving connection between the end of the cam shaft and the pump driveshaft.
