Graham, I didn't see any response on you alky leak, or I may have missed one. Alcohol has a lower viscosity, does it not, and it is lighter than water with less surface tension too so it will leak out of a pin hole where water may not.
Close the feed valves and put air in the tank and submerge it in water or gin--whichever is handiest. The bubbles will tell you where the leak is. Then drink the gin while you fix the leak. I had a leaking tank on a Finescale 48XX and that is the only way I could find it. After that show, I performed the test whether the tank was leaking or not--Hic!
