I like it. I was caught unaware when I was using one of those fluid transfer pumps, I needed to replace 2 quarts of something so I bought 2 quarts but forgot that the pump needs fluid in it in order to pump, so I ended up pumping in what I could then putting the input hose in to my old fluid to pressurize the pump as it pumped in the remaining new fluid which was still in the hose/pump. It worked, but was a mess because I had to figure it out on the fly with oil dripping everywhere.

 

Is that the 1730?

 

It's not hard to make a more affordable version via a garden sprayer you can pick up from your local hardware store. Piles of videos for instruction on how to make them.

I use mine (a modified garden sprayer) for pressure bleeding the brakes or flushing brake fluid (must have an adapter that fits the master cylinder reservoir) and most recently for exchanging the automatic transmission fluid on a sealed transmission (about 14 quarts worth of fluid).

Love it.
