   How much pressure does a pump put out you may ask? I will provide the information to you copied directly from my website "A pump pushes 5.4 to 8.25 PSI or 37.23 to 56.88 kPA into the Actuator and then holds it at least 3 minutes. If a pump is coming on and off it can exceed the factory inflation specs while stressing out the actuator (balloon/Bladder within Differential) causing the actuator to fail. I find  a Lot of bad used pumps out there for sale advertised as good."
