Since the subject of fuel line routing came up I figured I would throw in a few shots of my fuel line routing with my 6.3gal Accerbis. I tossed the plastic T-fitting right away and purchased a brass T-fitting to replace it. I also purchased a chunk of automotive hose that would just slide over the fuel line to protect the fuel line from rubbing and add a little heat protection. (the spring loaded clips aren't installed in these shots). A few snap ties and a inline filter and it's ready to go.
I also decided to cover the underside of the tank with adhesive backed heat shielding, should help to keep the fuel a little cooler.
