I can only imagine that this somehow tells you the fuel level in the tank being that I have a fuel gauge. But what exactly is this thing? Where does it connect to? It's on the right side underneath the gas tank on my ninja. It's been un-hooked ever since I had the bike so it doesn't cause and major running (or leaking) issues that I know of. Honestly I'm 99% sure its for the gas gauge but what does it hook up to?
