misunderstood the explanation but the theory of why this happened seems
unlikely. The sudden expansion of coolant would have to be incredibly
fast to cause an overpressure due to not being able to get out through the
overflow tube fast enough.

I just learned it
was a ¼” line; i.d about 1/8”. Trying to squirt a pint or more through
that in; what; less than a minute? That could do it. I currently have a
¼” line on mine as an overflow from the pressure bottle. The pressure
would release from the cap (through the upper gasket) but I would lose coolant
in a similar scenario. I’m going to rework that to a 3/8”. That
will give 4 times the flow area.

I guess its still not clear to me how that
situation would cause a line to blow off. The max coolant pressure
I have seen was around 24 psi and that should not cause a line to blow off
unless it was inadequately clamped or some other defect. Hard to believe
the pressure increase due to the heat build up would be that fast. But,
a larger flow area should indeed relieve the pressure build
up.
