Engineered specifically for 2003 through 2007 Dodge Ram 2500 and 3500 trucks powered by the 5.9L 24-valve common-rail Cummins turbo diesel engine, the Genuine Bosch Fuel Control Actuator (Part # 1 465 ZS0 062 / 1465ZS0062)—commonly called the FCA, MPROP, or Fuel Pressure Regulator—is the primary metering valve governing common-rail fuel pressure. Mounted directly on the back of the Bosch CP3 high-pressure injection pump, this pulse-width-modulated (PWM) solenoid meters low-pressure fuel entering the high-pressure pumping chambers based on direct commands from the engine control module (ECM).

Over hundreds of thousands of miles, fine particulate debris and fuel varnish score the actuator’s internal piston and bore. In addition, internal electromagnetic winding fatigue causes the valve to stick or respond sluggishly. When the FCA sticks or fails, typical symptoms include a fluctuating or hunting idle, engine surging under steady cruise, hard-start or long-crank conditions, rail pressure overshoot/undershoot, and diagnostic trouble codes such as P0087 (Fuel Rail Pressure Too Low) or P0088 (Fuel Rail Pressure Too High). Installing a genuine Tier-1 Bosch 1465ZS0062 restores steady fuel delivery without requiring a costly CP3 pump replacement.

Key Features & Benefits

• Genuine Tier-1 Bosch OEM: Manufactured directly by Bosch in Germany to original factory specifications—eliminates the premature failures and sticky plungers common to cheap overseas knockoffs.
• Cures Idle Surge & Pressure Hunting: Restores smooth, stable common-rail pressure at idle, cruising speeds, and wide-open throttle (WOT).
• Solves Hard Starting & Long Cranks: Ensures correct fuel volume fills the high-pressure pumping elements during initial engine rotation.
• Direct-Fit Replacement: Features factory Bosch electrical connectors and mounting bolt spacing for a straightforward 10-minute installation.
• Updated Bosch Packaging SKU: Supersedes original Bosch production engineering numbers 0 928 400 666 and 0 928 400 481.
• Zero Core Charge: 100% brand-new outright component requiring no core deposit or return.

Vehicle Fitment & Technical Installation Notes

• 2003–2007 Dodge Ram 2500 – 5.9L Cummins 24V Common-Rail Diesel
• 2003–2007 Dodge Ram 3500 – 5.9L Cummins 24V Common-Rail Diesel
• Fits Model Years: 2003, 2004, 2004.5, 2005, 2006, 2007
• CP3 Pump Fitment: Fits all original equipment Bosch 5.9L CP3 pumps (0445020011, 0445020039, 0445020147, 0986437304) and stock-based aftermarket performance pumps.
• Diagnostic Verification: Because common-rail CP3 pumps operate as normally open, unplugging the 2-pin electrical connector from the FCA will command the pump to maximum default pressure (~23,000–26,000 PSI). If rail pressure spikes instantly to max relief when disconnected, the pump itself is mechanically sound and the surging issue is caused by a worn FCA.
• Installation Tip: Clean the rear cavity of the CP3 pump thoroughly before unbolting the old actuator using a T25 Torx driver. Coat the new pre-installed O-rings on the 1465ZS0062 with clean diesel fuel or light engine oil to prevent pinching upon insertion. Snug the three Torx retaining screws evenly in a cross pattern (do not over-torque into the aluminum pump housing).
