Here's an update. I had the wrong line shipped to me from InlineTube so I am now waiting on the correct line to get here. One the plus side, InlineTube mde it right and sent out the correct line without any issues. It's good to deal with vendors who don't yank you around.

Since the opening on the fuel return port on my vapor separator is around .110" which seems to be larger than the recommended .060" people here have recommended, I got a piece of 1/4" brass rod and drilled out a 1/16" hole which is right around .0625". I inserted this restrictor is a piece of 1/4' fuel hose so I'm ready for my return line when it gets in.

I custom bent a 5/16" SS hard line from the VS outlet to the carburetor feed line inlet. I am hoping heat won't be an issue as this line does not touch anything at all so no direct heat transfer...
