Fuel Return Line - Do I Need One?

In the 80's they started using a fuel filter with an extra nipple sticking out the side. That nipple was connected to a return line. Those fuel filters are still available at most stores. That would be the easiest way to do it. I wonder if Fine Lines offers the older A-body lines with a return? If I remember correctly, my fuel line runs right through a very small hole in the torsion bar x-member. I doubt there is enough room for an extra return line. Obviously I could drill the hole larger.

A few people have mentioned that they have a filter BEFORE the fuel pump. I've always read that it's not a good idea. The mechanical pumps are good at pushing fuel, but not very good at pulling fuel. I've read of starvation issues that were traced to a filter installed BEFORE the pump. The sock in the tank is all you should need.
