Mark, Most of my info came from Woodrow, who put ink into lengths of tubing and watched it drain out as air (or vapor) filled the tube. Yet tygon did not do that. So, I guess we are all still experimenting. I had tried to lower the tubes but leave the tanks at nozzel height. This made each end high, but did not stop the leaks. It seemed that as long as the ink was at more than one height, there would be high and low pressures on the ink and that would either suck air in or create vapor. Maybe we don't have the final answer yet, but I definitly want to try the tygon tubing. The leaks are so slow and vary so much between colors and between different installations, that I will have to wait and see if I can find a solution. It sure sounds like tygon tubing is good insurance and if changing tubing fixes the problem, then how could it be any thing else but bad tubing?? We shall see.
