What I have used reliably for over 10 years in my commercial repair shop is
an ordinary 1/2 gallon garden sprayer. Yep, that's right! Toss the sprayer
end, instead, connect the hose to a fitting screwed into a spare fluid
resevoir cap (this would need to be the older type with the level sensor),
fill 'er halfway with fresh fluid, and pump the handle 20 or 30 times. Then
open the bleeder valve, and let the fluid flow! (If you connect a clear hose
to the bleeder valve, and into a container, you'll have less mess)
