My coach is tag-less.

Re; Forest's suggestion which is a good one. As noted in a previous postings in this thread I've already replaced the tubing from the 6-pack to the ping tank and the air lines from the ping tank to the airbags. The airbags are not leaking. I also have switched the air lines at the 6-pack and the problem stayed with the left side; they were then returned to their original positions. The air bags on the left are inflated to a pressure above those on the right even though the left side does not rise as the right side does.

I'm sure when the solution finally is clear we'll all be smacking our heads and saying: "well, duh". In the meantime I really appreciate your continued contributions to the search for the solution. This is just weird and very frustrating to me as someone who made a career out of troubleshooting.
