I took it to mean the rubber lines. The rubber ones are easy. You can get a new set from **************.com for $50. It's pretty straight forward. In the engine bay you simple pull them all off and put the new ones on. If you are doing the rubber lines at the tank you need the tank to be as empty as humanly possible, or else you have to wait a long time for it to drain out. Then pull the old lines and put the new ones on.
Then pump the primer handle and crank her up.
