'13 Blackline Question
I don't know if this applies to all newer bikes but my Blackline has a tube, that goes under the gas tank center divider plastic cover. The tube is about 3/8" diameter. It connects to a smaller tube, about 1/4", just in front of the gas tank by a small connector. They're just pushed together with no clamps.
There's nothing in it, like gas or oil because it came apart. And it didn't effect the way it ran. I did notice my gas gauge is "off". When I filled up, it use to go as high as 220. Now it tops at 190. Other than that, I can't imagine what it's for.
What does this tube go to, in both directions? Other than taking off the center "console" cover, I thought I could get an answer here. I'd Google it but I don't know what words to use for a search.
Thanks in advance.

That is the fuel tank vent line. It goes from a nipple on the plate under the console, down to the fuel vapor canister near the rear shock under the bike. When that line is disconnected, it creates the possibility of a vacuum leak at the throttle body. Either reconnect it, or leave it open, and plug the nipple on the throttle body.

As for your fuel range, maybe your mileage has degraded for some reason? Maybe different fuel?

It's not really the mileage, it's when I fill it up. It doesn't register as much as before on the gauge. I used to fill it up an inch below the fill hole and it'd show 210-220. Now, I can fill it to where it's touching the fill hole and it only shows 190.
