don't know the answer but if you do an ebay search for e.g. "10an fitting" you will get results including some from 'Torques' - thier name is in the pictures. all thier hoses list the ID and OD and even though they aint cheap, its easy to work out what hoses fit with which fittings and stuff arrives next day. all they sell is motorsport stuff - no affiliation with them but I've bought tons of stuff and they provide A1 service
