Well, once again frustration got the better of me. I finally managed to get a good bubble flare on the end and have worked the lower fitting up to it. It took several tries as the tubing kept sliding down instead of being forced to flare until I put a wrench on the block to get it really tight. Yes, unfortunately, the connection between the tubing and the hose simply would not break free so I had to cut the tubing just below the fitting. The right side loosened easily so it's just a matter of putting everything together. This part of the project has been a challenge but I'm finally seeing light at the end of the tunnel.
