• Other Names:

  Brake Vacuum Hose, Manifold Vacuum Supply

• Description:

  This genuine Ford brake vacuum hose supplies engine vacuum to the power brake booster on the 2.5L four-cylinder engine, cataloged by Ford as the brake vacuum hose. It fits the 2010-2012 Ford Fusion with the 2.5L Duratec engine. The hose connects the intake manifold vacuum source to the brake booster and often incorporates a check valve so the booster retains vacuum for consistent, low-effort braking. Drivers replace this hose when the rubber has aged, cracked, or split, when the fittings have loosened, or when a hard brake pedal, hissing sound during braking, rough idle, or a vacuum-related check-engine light indicates a leak in the booster supply line. A failing check valve in the hose can also cause the pedal to feel firm on the first stop after startup. Restoring a sealed vacuum path returns normal power-assist feel to the brakes and eliminates the unmetered air leak that a cracked hose introduces to the engine. This is a direct-fit factory replacement routed and molded to match the original. During installation, confirm the check valve orientation, seat each end fully onto its port, and secure the connections so the line cannot pull loose under engine movement. Inspect the grommet at the booster and the manifold fitting for cracks before completing the repair, and verify the 2.5L application.
