just bought a 1 gallon "roundup" brand sprayer at Lowes today..... used it to make a pressure bleeder for the brakes on my 58 2-ton! Works great, tank on sprayer is rated for 40 psi, and is see-through! I spent less than 20$ and have a pressure bleeder!
I also bought 10' of 1/4" ID clear PVC tubing. I used the adjustable nozzle from the sprayer, took the screw-on end cap off, drilled a hole in the end of the inside part, and pushed one end of the tubing on it (heated it a bit with my heat gun first). http://i1152.photobucket.com/albums/p494/69B-Cuda/brake%20bleeder_1.jpg
that part sealed tight enough, it did not leak. I then took an extra master cylinder cap and did the following:
1.Remove the splash shield from the inside 2.Drill a 5/16 hole in the top 3. weld up the vent hole in the cap
