Fuel Cap Hose

Postby fnickel » Sat Apr 26, 2014 10:40 pm



Just noticed a loose line while reinstalling my alternator on a '92 SE. It is the line coming from the fuel cap, and the end was hanging loose where the alternator resides. There is a T fitting near the end. Is it supposed to be attached to something else, or is it supposed to just hang loose? I'm guessing it might just be a vent line, but why would it have a T fitting near the end?

Also, does anyone have an owner's manual which describes how the vent controls work? eg. how to get warm air through the fairing vents, or cold air, how to control these features. If anyone could scan and post these instructions from the manual, or describe them in reasonable detail, that would help. Thanks.

Vents; turn the knob upper right side of the fairing and then if you lift the lever at the vent it opens or closes the circuit from hot to cooler air.

One other thing I just remembered from last year's riding season. I would get a smell of fuel in the garage where the bike was parked, for about a day after riding the bike. Would this possibly have anything to do with the vent line from the gas cap not being connected to anything on the other end? There were no other signs of leaking fuel that I could see that might have contributed to the smell.

On California-spec bikes, that hose connects to a charcoal canister. On non-California bikes, the end of that hose just hangs down, not connected to anything.

WingAdmin ,On Cal bike do you have to have the hose connect to the charcoal canister, If you disconnect the hose from the canister will it have any affect on the way it run. Cause sometime when I'm in the highway my bike losing POWER an I open the gas cap an bike takes OFF what going on here this happen once in a while.

I had the same issue, is caused by a build up of pressure from fuel vapors and the cap not venting right. I soaked my cap in carb cleaner and that took care of it.

Thanks, WingAdmin. My mind will be at ease now, knowing I don't need to connect that loose hose to anything.
