Hi Guys, If you leave the hose hooked up and not attached to a wheel with the pump off it will defalte the air bags. If you drive with it attached it will also deflate the airbags. I had a slow leak flat and I thought it would be easier to leave the hose hooked up to the infalter port on the H2. Well to my suprise in less then a block my rear suspension deflated. I noticed as I was driving prior to that the hose was hissing the air out. So use the air with the truck running and wait for the air suspension to level then hook up and inflate.
