The fuel line should not be steel or copper. There is an excellent Cupro line available that will last you forever without trouble. To go original, which is good also, get it from C&G or Roy Nacewicz, or several others. The flex line to get is fuel resistant, available from Shewman. The safety issue mentioned is the possibility of the electric pump running on after shutdown, or after a wreck. Various switching methods are available to prevent those events.
