Yeah, pin hole in fuel line is no good, fix that, lol.
For your lights, if high beam works but not low, the problem is likely somewhere between the switch and the bulbs. I'd check the bulbs first, that's easiest. Though if both left and right low beam went out at same time, it's likely not the bulbs. I'd check for voltage with a multi-meter at the bulb connectors (low beam is dark-green/yellow wire on my 2012). Try cleaning the switch up good, trace the wires from switch to bulbs looking for shorts. Start with that and see what you find.
