Restore precise fuel delivery and optimal CP3 pump operation with this New Bosch Fuel Control Actuator (FCA), part number 0928400535, for 2001–2004.5 GM/Chevrolet 6.6L Duramax LB7 diesel engines.
The Fuel Control Actuator is a critical component mounted to the CP3 injection pump. It regulates the amount of fuel the pump delivers to the common rail system based on engine load and demand. A failing FCA can cause hard starts, surging, rough idle, poor fuel economy, and even DTC codes like P0087 (Fuel Rail/System Pressure Too Low). This genuine Bosch unit is a brand-new OEM replacement, not remanufactured, ensuring factory performance, reliability, and fitment.
