leversole Posted May 6, 2013 Share Posted May 6, 2013 On my Superliner, the rear air system always has 5-10lbs more pressure than the front (green needle always higher)...through various tests, I believe the gauge is accurate. This truck has a lot more complicated system than the B and I do not fully understand all of it...Is this a problem that can be tracked to one of the check valves or something between the systems? Some other valve that is hung up or something?ThanksLeslie Quote Link to comment Share on other sites More sharing options...
