Uhhh...... missing that the term "rust" is just a non-technical term for ferrous metal corrosion?

To be precise, the stuff in my reg/O2 lines/solenoid was a powdery, white/bluish substance. It might be the same "thing" as "rust", but looked different enough to me...
The question is: why did my solenoid fail/block-up closed? If the substance was plain o' rust, why didn't it block open with the big stuff/rust flakes?
Joe Radomski helped me clean up my O2 tank after the wet O2 contamination, that's where it started, in the cylinder. Maybe it's really aluminum oxide? Either way, it was caused by moisture and O2 mixing in the O2 cyl and moved on downstream to the solenoid. That's my empirical observation and I'm interested to know what difference there is btw the 2 things-the powdery light colored stuff and the coarser, flakey red stuff... -Andy
