any auto parts supply or big box retail store like "Wal-Mart" auto section will stock them. It is called a (vacuum) "brake bleeder kit". Looks like a mini-version of a caulking gun with a bunch of short hoses that attach to it. You can just buy a couple of those cheap plastic funnels sold in various sizes in the same section. The pump only costs around $20 and the funnels less than a $1.
Just use caution with the pressure you use. You can generate enough vacuum pressure to suck yourself out like an inside-out pool toy if you are not careful ! :D

:D 5-10 minute sessions can produce results. But just like beauty...it fades quickly...
