Whats next?

Where do I Go? We finally got the Front Bags changed on my truck.I have checked for leaks on the front bags 2 times to find no leaks.I leak checked the fittings on the back of the guages yesterday.I am going to leak check these fittings again today.I aired the whole system up front and back.The back did not go down at all.The front air guage read 0 for air pressure.The left side or driver side was all the way down.The passenger side was up It still had about an inch to come down even though the guage read 0.When I hit the switch you could feel the passenger side go down about an inch.Whats next?Are the small lines that run to the guages usually solid with no joints to check?Should I go to the back valves?

check the valves, use soap and water on the fittings and the body and the activator (the part that the plastic thing goes onto).

Could be your dump valve(s) is it a 2 or 4 way system? What products do you have? New or used?

Do you have the valves in the correct direction?

Do you have any check valves that are facing the wrong way?
