ABSTRACT:
A fuel pump drive system for an internal combustion engine uses a cam-to-cam gear from a double overhead camshaft to rotate a fuel pump gear. The fuel pump drive system may have a primary camshaft, a secondary camshaft, and the fuel pump. The primary camshaft has a camshaft gear and the cam-to-cam gear. The secondary camshaft has a cam gear. The cam gear engages the cam-to-cam gear. The fuel pump has a fuel pump gear that engages the cam-to-cam gear. The fuel pump gear drives the fuel pump.
