Fuel pump return line

Hey people, so I started plumbing the fuel lines on the engine and I think I may have a problem. The tech guy at JEGS recommended the JEGS 110 gph mechanical pump (which I bought) but on their website it says "Not for use on carbureted vehicles with vapor return lines". I only noticed this when looking for some an fittings. So now I'm fairly confused about how to resolve this. Looking at the other mech pumps holley, edelbrock etc.. they don't mention anything about about a vapor return line. Any sugestions?

Here is the solution I came up with, 130 gph Holley 12-327-13 the engine builder said no to the 110gph pump, a 12-803BP pressure regulator and I decided to get a fuel pressure gauge. I'm going to use the stock lines running from the tank. Blocking off the Tank Vapor return line just wasn't kosher for me. This link helped out a bit. Hope this helps anyone else. http://www.holley.com/data/Products/Technical/199R7914-3.pdf

So I found this post way way down in the back about fuel pumps and fuel vapor return lines. Which only goes to prove how smart the collective here is. To bad I didn't take more time searching for it this morning it would have saved me a day. The information I am getting here is going a long way toward getting my project completd. Thanks to all
