Many customers have been asking for gas lines for their Cubs. We have been explaining that the best way to go is to purchase the fittings and gas line tubing at their local hardware store.........and then make up their own gas line. However, sometimes these fitting are hard to find, so we have acquired a source for them and are now offering them to you. All you need is one of these fitting/ferrule sets for each end of your gas line. You will need to buy 5/16" copper tubing locally and cut it to length. These fitting are correct for attaching to both the sediment bowl (on the tank end of the line) and to the carburetor. This is assuming that no non-original adapter fittings have added to the tractor.
