Engineered specifically for 2011 through 2016 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.7L Powerstroke V8 turbo diesel engine, the Genuine Ford Brake Booster Vacuum Pump (Part # BC3Z-2A451-B) supplies the necessary negative pressure to operate the power brake booster. Because diesel engines lack natural intake manifold vacuum, turbo-diesel applications rely on an engine-driven mechanical vacuum pump to provide power-assist braking capabilities.

Over high mileage, internal pump vanes, drive gears, and shaft seals wear down, leading to a hard brake pedal feel, delayed vacuum recovery, and oil weeping around the pump housing. Part number BC3Z-2A451-B represents the authentic Ford factory replacement, ensuring correct vacuum draw, factory line hookups, and dependable braking safety with zero core charge.

• Installation Tip: Disconnect the negative battery terminals before servicing. Disconnect the brake booster vacuum supply line carefully from the pump nipple to avoid damaging the quick-disconnect lock tabs. Unbolt the mounting fasteners, swap the pump assembly, and ensure the internal drive gear or coupling engages properly. Torque mounting bolts to factory specifications and inspect the vacuum line check valve for proper operation.
