41-47 should be the same gas tank......there should be 2 outlets on the bottom of the gas tank........one under the passenger side on the bottom of the tank...........and one under the driver side on the bottom of the tank...........the one under the drivers side is capped and the one on the passenger side is used and a flex tube is screwed into gas tank there.....the hose then goes to side of frame where the solid fuel line goes to carb.....i hope that helps.........
