I had a leveling kit installed in the shop didn't connect a vacuum hose to a hub completely and it was sucking air. I drove 70 miles like this, could there be any long term damage? This is a brand new truck.

If you didn't get any check engine light then the computer probably richened your mix up to compensate. So you should be ok. Here are the 4x4 wiring diagrams so you can see how the system works. Please check the fuses in the diagrams to make sure everything is okay.

Check out the diagrams (Below). Please let us know what you find.
