• Description:

  This genuine Ford brake vacuum hose, catalogued as JL3Z-2420-AB and also listed as a vacuum tube, supplies engine vacuum to the power brake booster on 2017-2021 Ford F-150, Expedition, and Navigator models built with the 3.5L twin-turbocharged EcoBoost V6. It carries vacuum from the source to the booster so the booster can multiply pedal effort for power-assisted braking, and includes the molded routing, fittings, and any integrated check valve or connectors Ford specifies for this engine. Drivers shop for this hose when they notice a hard or high brake pedal that requires heavy effort, a hissing vacuum leak near the booster, rough idle or a stored vacuum-related code, or a cracked, collapsed, or oil-softened original hose that has deteriorated with age and underhood heat. Because a leaking or split booster hose reduces braking assist and can affect engine idle, replacing it with the correct Ford part restores full power-assisted braking and proper sealing. This hose is built to the exact length, routing, and fitting geometry Ford designed for the 3.5L EcoBoost application, so it seats without modification. During installation, confirm the check valve orientation if equipped, fully seat each connector until it locks, and verify a firm brake pedal and stable idle with no audible leaks before driving. Using the genuine Ford hose preserves correct fit and braking performance.
