Mostly cosmetic really, also it's a minor thing, but it's difficult to tell with the black one, which air-flow hole is open
For me it's not so much leaking as it was seepage. After the first tank there'd be a thin film around the airflow ring, after the second refill it'd get worse, and so on. I'd have to keep wiping it off. I mean I guess that was leaking technically speaking, but it wasn't like it was flowing out. Now that I've tightened the positive post down it's been dry and I'm loving my Siren all the more.
Thanks guys, i did gloss over the posts re. the fix. If i have any issues re seepage/leaking , i will read more carefully. I had the same seepage issue for a couple of days with one of mine, but it took care of itself for some reason. All i can think i did differently was to tighten it up more forcefully when re-assembling.Not leaking/Seeping any more. Read back in this thread for the fix we found for the Siren. I just re-built my 22mm early yesterday afternoon (05-22). I had 21 tank fulls thru the same build when I did my re-build, and not anything more than some condensate every few tank fulls that I wiped off from around my air flow ring with a paper towel.
