I ordered a new seperator but it's slightly shorter/smaller and its a manual drain type instead of the auto drain.    The diameter is same size so I just put the new one in place of the old one.  The leak is gone now but I was wondering if this new one should be exactly like the one I'm replacing or am I ok with the smaller seperator?

I assume it doesn't matter but just thought I'd ask.  

Thanks!

Shouldn't matter you'll just have to remember to drain it manually. The older one is longer because of the float. They should both hold the same amount of water.

Thanks Forest
