High Pressure Fuel System Flow
• Fuel is supplied to the high pressure fuel injection pump
after being filtered by both the HFCM (horizontal fuel
conditioning module) and the engine mounted fuel filter.
• The high pressure fuel injection pump is gear driven
off of the camshaft gear at the rear of the engine.
• Once the high pressure fuel injection pump
pressurizes the fuel it is routed to two (2) high
pressure fuel rail supply tubes, one for each bank.
