The main thing to worry about when using rubber lines for anything is chafing and heat. As long as it's not rubbing against anything or next to a heat source like the exhaust, you should be ok for years to come. I do like to keep the lengths of rubber hose to 6" or less, as the shorter it is the less chance for something to go wrong. If you do have to run it through a hole in metal, put a piece of vacuum line, cut down the side, as a grommet. You can make grommets any diameter you need and it's cheap. Small diameter vacuum line works great for this.
