Are you able with a thumb to push down a new lifter plunger that I had soaking in oil for 1 week? The old ones I took out won’t budge. ( the plunger).

Soaking won't do much to fill them. Get a mason jar. Put a Schrader valve in the lid. Throw the oil and lifters in there. Suck the air out with a mighty vac. You'll see all the bubbles come out.

Never tried that.. Next time i will.. thanks..

EDITED: I have this set up with this older vacuum pump where I took a jelly jar that has a good sealing lid and put a couple ports in it and hooked up to plastic pneumatic lines.. I have an attachment of a 1/4" x 30" soft copper line for it to to be able to suck all the fluid out of my Forks..

so I tried it with the lifters put them in there and fill it up with oil and pulled it down to at least 18 to 20 inches of vacuum and man I couldn't believe how quick the air came out of the lifters. Almost look like boiling water LOL.. And it only took a few minutes.. thanks..

When they manufacture the lifters they use a very light assembly oil, just enough to coast everything.. They never come full of oil..

That vacuum idea is pretty slick. Never gave it that much thought, but it seems like a no brainer now. Thanks for the info and idea.

Well the vacuumed worked 100% on one lifter. About 60%on another and maybe 20% on 2 these firs don’t want to bleed down.
