Hi Dennis. Thanks.

Was just thinking of that on the way home. Like even if this Westy had sat idle for a year or 2 with a half full tank, IMO, it's a stretch to imagine that enough, or any, condensation would create any amount of water in tank.

I think the lines to expansion tanks are original; braided hose, no clamps. It's possible the tank was, or is, leaking at the filler tube O ring seal at tank. There's tell tale drip pattern below filler tube at frame. It may be safe to guess that the tank has never been resealed.

It's likely the tank will need a reseal. I know Bentley outlines the pressure test procedure. I wonder if I could adapt an old filler cap to my brake pressure bleeder? (air pressure bleeder, no brake fluid ever in it). https://lh5.googleusercontent.com/-OR70veLBm-Y/S65YmscQjyI/AAAAAAAACmg/6-oJ_lH27ZY/s720/BrakeBleeder_Pink.jpg

I can check pressure in bleeder via valve I installed.

Neil.
