Old tank and new one has a different neck size also.

Correct - I sandwiched my tank in so it would go any further "up" or that would have been the case. I also ended up putting some brackets between the two crossmembers to aid this even more. They run the same way as the frame. For the filler hose, I just double hose clamped the hell out of both ends. Someone showed me a link to some flared hoses at one time but I don't have it anymore.
