With the new sending unit in place, I decided to use the stock 5/16-inch hard line as the return since it runs from the tank up to the firewall. Since the original connection used a flare nut to connect to the line on the stock sender, the tubing was already flared on the end which allowed me to use a piece of tubing to mate the two ends. Normally, I wouldn’t prefer this method as it means having a short piece of hose in the cab, but since the feed line on the new sender will require the same connection, I made the concession to do the same on the return line. This kind of connection is fine as long as both ends of the hard line have a sufficient flare or swage on the end to keep the hose from sliding off the end once clamped in place.
