This is the check valve. There is a metal ring/cap that goes on the end of the nipple and keeps the valve in place. The metal ring stayed in the flex tube when I pulled it off. The valve can be easily pulled out when the ring cap is removed.

Don't know if having the return line conected to the sock would make much difference.

As for the return line to the strainer. The factory setup might help to provide fuel to the pump under low fuel conditions for short periods when the strainer may not be immersed in fuel. Does the factory strainer fit on the Walbro? I think the strainers can be purchased separately(according to the GM service manual).

There has to be a check valve on the pump or between it and where the fuel line exits the tank module. I don't see a separate one in the diagram in the manual. Is there one visible on the factory pump? It might be internal. Here's an excerpt from the manual:
