What were the lines originally? I'm pretty sure the '46 216 tank to pump line was 1/4" and the pump to carb line was 5/16" as I previously mentioned, but I need a need a confirmation of this as this truck had 5/16" tubing used for both lines. I know the '41 trucks had 1/4" tank to pump lines and I'm pretty sure the '46 was the same, wasn't it? The little flex hose (from the parts suppliers) from the tank valve has an adapter on one end to screw into the flare fitting for 1/4" tubing. That's another indicator the line should be 1/4" and not 5/16".
