my Neon's gas tank filler neck is extremely rusted. i have begun the search for inexpensive ones online, but i got to thinking today when i was starting to remove the old one- could i just go to a hardware store and buy the correct length of rubber tubing, and use that? or will that be a serious safety issue as far as fire and explosions are concerned? i noticed that there was a ground cable screwed to the car frame, so i assume it is there to prevent sparks. i would assume that a steel or aluminum tube will be no better or worse for sparks than a rubber one would be.
