I removed the fuel tank on my Trophy 900 to change the spark plugs and wires, so I had to disconnect some hoses and wires. Next to the fuel level sender is a pipe with a rubber hose attached to it, that leads somewhere into the unknown, down along the main frame tube in front of the battery area. I haven't figured out yet where it goes, but I need to replace it as the end that attaches to the fitting on the tank is split. Is this some kind of vent tube or ? It looks like vacuum hose. I'll try to attach a photo of the bottom of the tank. Thanks!
