1/4 and 3/16 are the sizes. Be forewarned though, you'll need to salvage the fittings off of the original lines for some of the connections. The generic straight lines from the parts store are the right diameter, but the fittings sometimes are wrong to screw into the prop valve. The GM fittings are thicker to make the 3/16 line screw into a larger hole.

Just clean em up and put them on the new line before you flare and bend it.
