Summary

If you have a vacuum pump at home, you can bleed your HD lifters very easy. Just find a glass jar with at least 70mm or 2 3/4" opening, fit the lifters inside this holder and fill with oil. Drill and connect vacuum hose to the top of the jar and wait for the bubbles.
You need to print 1 piece bottom, 2 piece top from the files. Take a long M8 or 5/16" bolt with 13mm or 1/2" hex head for which there is a pocket in the bottom part. The bolt should be at least 90mm or 3 1/2" long. You can put a nut on the top to prevent the 3 parts from rotating.
