Should it be metal, or is a steel braided hose ok? I had a -6an braided line on before, but read about possible issues (its been to long to remember what), and changed to a 3/8 hard line some time ago. Tonight, the damn line had a little wet fuel spot so i tried to tighten it and it poured everywhere. So now my memory is to fuzzy to know if i should replace it with another hard line, or put the braided line back on? :shrug
