Fuel Lines? Where do they go??

I keep getting this sucker closer and closer to the road, and my next step is fuel delivery. Can somebody give me a play-by-play of how that should go?? I have some (what appear to be) lines in a plastic bag that came with the bike, but I've got no idea how they should go. Any suggestions or ideas would be greatly appreciated!!

I'm planning on doing standard plastic tubing from the lawn tractor store - that should be okay, right??
