The vacuum pumps and vacuum bottle were gifts from fellow EV Builder Tom G. (Thanks Tom!)

Apparently, I have worked on this project so long, and bugged so many people about it, they now just approach me with junk for the project!



The vacuum pumps are both German-made.

The one on the left is a double-pump and runs on 12 volts. Either pump can suck or blow, but the blowing end on the one pump has the connector snapped off. (Fine by me! I just need suck!)



The pump on the right is a 24V pump. It has two hose openings, marked P and V. I assume these are for "pressure" and "vacuum". I tried running it on just 12V, and it seems to work fine that way.



The Vacuum bottle is just plain cool. WAY nicer looking than some PVC pipes with end caps! The end of it has a T with two different size openings. The bigger end also has a shut-off valve.



Real busy these next couple days. Hoping to work on the car some more this Sunday.
