If you go for the fuel filter with a vapor return fitting, make absolutely sure the return nipple has a restrictor orifice in it, it's about 1/16". Some of the filters coming through now have been cheaping out and not making them with the restrictor in them. I've run into this issue with both Wix and Fram filters for sure so far- some have them, and some do not. Might be an old stock/new stock thing.
If you use one of the new ones, you can easily run into the situation where a standard pump can't supply enough fuel to the carb when most of the fuel is getting bled off through a wide-open 1/4" line. When I ran into this situation (after a lot of frustrated head-scratching) I ended up putting a 1/16 restrictor in the return line, and the problem was solved. Now I don't have to worry if the new filters have the required orifice or not.
