Those bleeder-vacs are BAD ASS.

So while fixing the tools. I noticed my MityVac wasn't working either when I went to test diaghrams for the air distributor. Decided to tear it apart even though the kit to rebuild it is $38 on fleabay. Tore it apart and the aluminum internals were all corroded and a bunch of nasty gunk in it. Hadn't used in a few years. Tore into about 100 pieces and started cleaning parts. Used a wheel cylinder brake hone at low rpm to clean out the cylinder real good. Cleaned all the internals with Hoppes No 9 gun cleaning solvent and steel wool. Replaced 2 O rings from my handy dandy HF $4 O ring kit. Blew out all the other orfices. Coated all the internals with a light coat of gun oil, reassembeled it and BAMM !!! It's working and holding strong vacuum now and not even trying to leak down. Before it would go up to about 4 and fall to 0 as soon as you were off the pump, so not only would it not pump up, it would hold nothing. Who needs a $38 rebuild kit?? NOT ME !!! Not yet anyway, maybe someday. This too is over 20 years old. It's a bit cleaner now than it was in the previous pics on the last page.
... I think the seller was EliteTint.
Scratch that. EliteTint is a valid seller just no listings at this time
