the plastic lines are 8X1mm PA12 nylon you can cut the old ones off the barbs and re-do them with new line and pinch clamps. i ordered 10 feet of PFA teflon 8X1 line and a pack of 5/16 to 3/8 pich clamps from Mcmaster to do mine. the PFA line is resistant to all fuels and chemicals and will never degrade. https://www.mcmaster.com/#52545k42/=1bdkibs https://www.mcmaster.com/#5733k76/=1bdkimi
