• Description:

  This genuine Ford brake vacuum hose, catalogued as JL3Z-2420-AD and also listed as a vacuum tube, delivers engine vacuum to the power brake booster on 2018-2020 Ford F-150 trucks equipped with the naturally aspirated 3.3L V6 engine. It routes vacuum from the intake source to the booster so the booster can amplify pedal force for power-assisted braking, using the molded shape, connectors, and any check valve Ford specifies for this specific engine layout. Owners search for this hose when the brake pedal becomes hard or requires unusual effort, when a hissing leak is heard near the firewall or booster, when the engine idles roughly or sets a vacuum-related code, or when the original hose is found cracked, collapsed, brittle, or softened by heat and age. A compromised booster hose reduces braking assist and can disturb idle quality, so installing the correct Ford-specified part restores full power-assist and a sealed vacuum path. Engineered to the exact routing, length, and fitting geometry Ford designed for the 3.3L F-150 application, it connects without trimming or adapting. During installation, verify the orientation of the check valve if present, seat each coupling fully until it locks, and confirm a firm brake pedal and steady idle with no audible leaks before returning the truck to service. The genuine Ford hose ensures correct fit and dependable braking.
