And just in case you missed Jeff's reference to "primer nozzle", you don't want just a plain fitting there, you need one with a tiny orifice in it. This does two things...sprays a fine stream into the manifold for better atomization, and in the event that the line breaks or comes off, it'll only be a small vacuum leak, not a huge one. Wicks sells what they call "AN4023 primer fittings", but you'll also need an AN800 code union for each one, as well as an AN805 nut. They are all right there together on page 153 of the newest catalog. These fittings are made for use with 1/8" copper line.
