And, back to the starting point of the solution to this problem, I created
a problem for myself when I slavishly copied the way the hose was in the
original car. That didn't work, in fact it caused the problem. There were
only two solutions: 1) fully understand the cooling system so that the
modification could be treated as the total effect of two new parts, the
tank and the hose, and not just the hose, or 2) get the advice of someone
who already did understand it. I was fortunate enough to have access to the
latter through this list.
