Thanks Scott and Karl.

Karl that was exactly my plan - all the heater lines were removed from my
bus by the PO (for good reason). He decided it was going to be a summer only
ride and so he made a copper "U" peice that goes from #12 to #13. Works
great - except that I need heat now :)

So I have a lot of 5/8 hose and some "T" fittings for reconnecting
everything but hadn't planned on the larger size of #13 - I wasn't able to
really measure it without removing that "u" part he made.

I guess I'll get some various sized x to 5/8ths barbed reducers - one is
bound to fit. I also guess I'll stick with copper.

Thanks again for your input gentlemen.
