Le Mans Bowl Fittings

I recently acquired a 4118 Holley, that came with the Lemans fuel bowls. However, the previous owner didn't use the correct fuel line. The steel line is the easy part. I would like to find out if there is a common brass solution?
Specifically sizes that I can order online?
I don't have easy access/knowledge of where to go buy, here in my new, temporary town in Hicksville, NY.
Thanks very much!

Thanks!
I thought I was on my way back over seas, and have now been living in NY for about a year. Everything I own, however is in Colorado...Can't work on the projects so not much to report on the boards that I do visit...
