X2 I found mine at a Good will store. I put added a vacuum gauge from an old ac gauge set along with 2, 1/4" male fittings. One to hook up a vacuum/evac. pump. The other one has a tube running inside to about 1/4" from the bottom inside to pull down/out fluids.I use it all the time. That sucker will pull a golf ball through a garden hose:cheers:
