uneven tire pressure buildup while towing with airbags

Hi Bryan, thanks for your quick response. The setup I have for the bags is a compressor under the hood of the truck that feeds both bags form a single line. The airbag gauge shows the pressure from that single feed line. I guess you have to assume the pressure in both bags is equal. I think my next step is to pressure up the bags and get under the truck and spray some soapy wanter on the lines and see if I get any bubbles.
