Fuel tank fittings

[hennypenny]

Hi all, does any one know what type of fittings are on a fuel tank for a Bavaria 31 from 2001? I need to attach to a fuel hose.
I think they are like this:-

If so what size are they? I am replacing the fuel system with a new Racor and new fuel lines the old ones were crimped. I am not intending on replacing them with crimped again.

Thanks a lot in advance for any help.
