Wells just told me you called and discovered the ink line has a tiny hole in it, from mice that apparently had found a home inside the machine (!)
Compass Micro is a good source to get replacement parts, but replacing an individual ink line is not an easy or quick task. Wells said you asked about taking the hole, and I think that’s worth trying before replacing the ink line! I would try a flexible but sticky tape to seal the ink line, without restricting movement.
Best of luck!
