Methods and systems are provided for mounting a fuel pump to a cylinder head of an engine. In one example, a mounting system may comprise: an engine fuel pump mounted directly to a cylinder head cap positioned underneath a cam cover, the cap including a raised portion having a first and a second cap mounting boss, and a main opening for directly receiving the fuel pump, wherein each of the first and second cap mounting bosses couple to a flange formed on a bottom portion of the fuel pump. In this way, the fuel pump may be directly mounted to the cylinder head cap to simplify assembly, minimize fuel leakage and reduce pump vibration.
