My experience is that leakage of chemistry is not an uncommon problem and the real trick is finding a lid and container that work together and don't leak. That being said, my suggestion would be to try to find a complete set that doesn't leak, rather than trying to find a lid that will work with your tank. If that makes sense to you, let me know and I'll go through my stash and see what I have. If that includeds a stainless steel single roll tank and lid which don't leak (and it probably does) it can be yours for the price of the postage on a flat rate box. I must ask if you have ever used a Patterson tank and reel set up. They are my preferred tool and I've used both Patterson and stainless. I have surplus stainless and not the Pattersons. Bill Barber
