6AN to barb fitting

[autronicDSM]

What size barb fitting works on stock rubber fuel return line? I'm just trying to install regulator with a least hassle as possible. If I can get this all I need is to order one of those fittings for fuel rail that has 6AN outlet and I'm all set.

Not sure what kind of regulator your goin to use but this is the best fitting found for the aeromotive fpr that I'm running. Scroll down to my post at the bottom. It will fit any reg. that uses -6an o ring fittings, screws directly into the reg without any other fittings and fits the stock rubber line perfect.

So it's a 7mm one. Cool. I searched for 2 hours last night and couldn't figure it out. I have a digital caliper but battery is dead so I couldn't go out and measure OD of the stock hard tubing.
