Cab Suspension issues

[Paccardude]

Hi,

I just installed the pro-ride on my 2015 prostar international. My concern is about the height leveling valve linkage. I only ask because I'm not sure if the last one was properly installed. I never saw the air bags go down and this would be after 2 weeks of sitting. The last install was sitting pretty much at a 90 degree angle. When it is properly installed should there be no air coming or going out when at 90? I'd like to get this new maybach cruising outta here by Friday.


please advise.
