HSP has developed a billet replacement front engine cover for the hard-core enthusiast. These beautifully machined pieces allow you to relocate your high-pressure fuel pump from the valley and mount it 180° in front of the motor. We also provide a second pump mounting location driven from the cam gear to allow two gear driver CP3 pumps. Due to the variations between specific applications, custom radiator fan and high-pressure fuel lines are required. Some additional benefits include being able to run up to three high-pressure pumps on the front cover. Also, steel CP3 mounting plates for a secure hold on pumps, room for larger intake manifolds due to CP3 relocation, and an oil fill hole for easy filling.
