The Filler Lock to the aux tank (in the barrel) failed by Port Augusta!! I couldnt get the key in the slot so couldnt unlock it! The key, a hammer and Leatherman soon sorted it though, I just have no lock now:mad:.
I too get the vacuum lock, but I havent found that to be a problem. I can however vouch that the tank is completely water-tight, even with the lock missing:D
I'll reply to your other thread.
