Yup my old vet syringe rubber got stuck at bottom, and I happened to be wondering around Wall Mart near the fuel jerrycans and found this.....

No rubber to get stuck on this one & it comes with a perfect clear hose.
Works very well and has multiple uses....
Here is a link for it..Hopkins Flotool Mixmizer
FloTool Gas and Chemical MixMizer: Motor Oil, Transmission Fluid & Car Lubricant : Walmart.com

Those are great to have and often hard to find. Might be worth picking up a half dozen if the price is right.

What are you going to be using that for?
Things like suctioning out some power steering fluid, so you can add some new fluid?

Yes William exactly!
Even though this was designed as a two strike oil to fuel ratio mixer, it works great to suction out the power steering fluid & makes it easy to install clean fluid again.
Old brake master cylinder fluid can be made fresh easily with this as well.
I bought a few of these and even keep one just for adding distilled water to batteries.

I replaced the fluid in my master cylinder as well, but I don't know how much it will help, since the fluid doesn't recirculate, at most a little more fluid goes in them as pads wear down.
Which is why eventually when I di my rear brakes, and replace the wheel cylinders, I'll replace the fluid with a flush.

With the brake master fluid William, my main concern is that it does just sit there and often for prolonged periods. DOT3 does likes to absorb moisture, so once a year I like to suction out the old brake fluid and replace it to the same level it was before. Of course having some brake fluid /copper content reading test strips is a good idea ! Phoenix Systems - Brake Strip
I just replaced all the pads/turned rotors on the PA and it has been 1 year now with the fluid in there without bleeding at all 4 corners. I guess I am due to remove the brake fluid in the PA & 4x4 again just as preventative maintenance.
It is interesting to use a clear glass bottle to place the old fluids into. It gives you an indication how the old fluid really looks, but dip your strips first anyways!
