Good lead, JJ, I see the boot in the drawing and will next remove the rudder for further inspection.
Thanks

I had the same problem in a Discus 2b - it was the rubber boot. You have to remove the rudder for access, but it's not a big job for someone experienced with this airframe.

Boot is usually the suspect. An hour's work for an experienced techie to
replace. Use non-acidic thick grease like vaseline to lube before putting
it in. Saves you smaller leaks over time. Problem usually comes back after
some years depending on tailtank use, local climate etc.

Just one small bit of advise when removing rudder. Make sure you have some
extensions made on the Rudder cables i.e. long plastic cable tie etc. as it is extremely difficult to fish the ends out of the fuselage if they slip into it by mistake.
