SAE J30R10 Source?

[dunk]

I used copper pipe and a compression fitting on each tank. File the end to a slight angle so it can't suck to the bottom.

If I only need less than 6" for each tank, than I single foot of 30R10 would be cheaper then new shower heads. I still have some time to mull it over before I tackle it.
