I really cannot not spend the time on something that has been replaced a few years ago. it just does not make sense.

Why do you need to buy a new sensor assembly if you already have one running good?

The methanol may be 99.85% pure in a sealed tank. But once open and mixed, anything can happen unless you have a controlled environment/clean room facility.

I am not a chemist. Didn't it be better to ask Jerrychem why their methanol produces bubble when mixed with Demin water. (assuming the dimin water is also 99.85% pure).
