Bleeds and pumps up hydraulic lifters Vacuum Tappet Pump-Up

This high-quality lifter bleeder tool is designed to pre-bleed and remove trapped air from hydraulic lifters and tappet assemblies — ensuring smoother engine startup and preventing valve-train damage. This version is made from a durable, oil-resistant 3D-printed material for superior strength and chemical resistance. Simply load your hydraulic lifters into the included basket, place it inside the vacuum jar, fill with clean engine oil, secure the lid, and apply vacuum (such as from a brake bleeder). You’ll see the air bubbles rise and escape, leaving your lifters fully primed and ready for installation. Features: Pre-bleeds and pumps up hydraulic lifters quickly and cleanly Prevents damage to valve train caused by unbled lifters at low RPM Holds up to four hydraulic lifters in a convenient tray Designed for use with vacuum bleeder systems Made from high-strength, oil-resistant 3D-printed material Includes: Basket, Jar, and Lid Compatible with Evolution Big Twin and Twin Cam hydraulic tappet assemblies Proudly Made in the U.S.A.
