914 rubber doesn't make the soft brake line grommets that secure the soft lines that attach to the hard lines that fed the master cylinder. I think they might be the same grommets as the fuel lines.
Thanks Brian

Chris Foley at Tangerine Racing has the fuel line grommets, which are the same as the brake line grommets.

thanks

If you are looking for the grommets that go into the master cylinder the above link is what you want. The other ones might be the where the lines pass through the body.
