Amazon product ASIN B0002SR7TC
When it works, I love it. When it doesn't...
Mityvac somehow is the big name in fluid transfer tools. I don't understand how, because of the three Mityvac tools I've owned, three were troublesome.
When the 7201 works, it's amazing. It makes changing the oil in outboard motors, engines that have both a dipstick tube and top-mounted oil filter (most Subarus, Toyota 4.0, Chrysler Pentastar, many Mercedes) a breeze and mess-free. When it doesn't? It's difficult to diagnose, Mityvac is no help, and replacing the two most common failure points costs all of $30 less than buying a new one.
I also owned one of these:
Amazon product ASIN B00MPQ8RBGEven though they say it can be used for various fluids, including brake fluid... don't ever actually use one on brake fluid... the o-rings swell up and it becomes useless, as well as nearly impossible to disassemble to replace them. Just buy a few dollar store turkey basters that you can throw away guilt free when the bulb fails and move on. If you want one of these for coolant, go for it, they'll work fine for that indefinitely.
But the same company that makes those pieces of crap? They also make this:
Amazon product ASIN B0002SQYUA
Mine's worked flawlessly for 7 years, used as a vacuum pump, pressure pump, and even as a vacuum gauge in a pinch. The clear door inside the case that contains the small parts broke 6 years ago, but that's the only complaint I have. It works, and works well. If only their quality control on their whole lineup was this good.
