How big should fluid lines be in a hydraulic system?
Under-sizing fluid lines will result in high pressure loss and system overheating. Over sizing lines increases the cost of the system. Lines should be sized as follows: Suction: 2-4 feet/sec. Return: 10-15 feet/sec. Medium Pressure: 15-20 feet/sec.
Do you have to bleed all four brake lines?
It’s common practice to bleed all four brake lines after opening any one brake line. However, if the brake line you open is an independent brake line, then no, you don’t have to bleed all 4 brakes.

By pumping your hydraulic piston control, you will force hydraulic fluid out of the lines and into the bottle. To remove fluid from a vehicle’s brake lines, you’ll need to pump the brake pedal.
How big of a tubing do you need to bleed a line?
The tubing should be clear and should be 3 inches long and 1/8-inch in diameter. Fit the tube tightly over the screw, tight enough that there will be fluid leaks from the cylinder, and that no air will enter the cylinder. When one end of your tubing is secured onto the outlet screw, place the other end into one of your bottles.
