What was done to my tank was cut the nipple off at the tank and use a metal thredded nipple to replace the plastic molded one

Well, the bottom line going to the carb where it is connected to the tank leaks on mine. Use wire and twist it around it tight, thats what I did to prevent it from leaking.
Here might be a better cure for your leak. The wire may cut into your line due to vibration. If you will cut off a piece of fuel 1/8 in length, then place the piece of tubing over the end of a closed pair of needle nose pliers. Open the needle nose to stretch out the tubing, then take your fuel line and place it thru the center of your stretched out tubing and release the needle nose. You should have your 1/8 over the very end of your fuel..then connect it to the tank...no leak you should find.
