i made a power bleeder out of a quart jar some 1/8 steel line neopreme tubing and a little aquarium valve i had sitting around it works great on a 1st time syst or to flush the old stuff out the line from the bleeder side steel tube is brazed in the lid which goes at the bottom of the jar, the vacume side is also the lid on the top, hook one line to the bleeder screw and the vacume line to a vacume port on the carb,Open the valve just a little . got to be carefull and be quick as it will suck a brake res dry pretty fast, takes no time to fill the lines
