I've looked at the stack very carefully so I know exactly what you mean by the inner and outer seals/ the lip on the manifold. It's really hard to get to seat - gonna try some to track down a silicone based lube thang. Trying to be forceful yet gentle cuz tracking parts for these things is getting tricky.
