Rubber hose

[lightning]

I got back from a ride today (Ohio--65 degrees and sunshine!) and noticed I was dragging a rubber hose as I backed into the garage. I am assuming that it is the battery acid runoff hose. The first thing I did when I bought the bike this year was put a new gell battery in and I never niticed a hose. It is black rubber, about 28 inches long, id of about five sixteenths, and has only been over a nipple on one end. It was wedged (not connected) between the battery case and frame.
Positive ID, anyone?
Thanks

You have most likely guessed correctly. If I were to describe a battery vent hose - well, you just described one.

Another hose similar to this is the drain hose that comes out from underneath the tank. This drains the well around the fill cap in case gas or water gets in there. My /7 has one of these hoses...not sure about all models.

But if you say the hose is wedged up around the battery, then it's most likely the battery vent hose for the lead acid batteries.

28" is pretty long for a battery drain hose. But it's just about right for the length of the tank overflow hose, and the 5/16th diameter. That hose should come down rom the right side of the tank on these models.

However, it would be odd for the tank drain hose to migrate that far back, unless it got caught up in stuff and pulled off while someone removed the tank.

Having done that, I can understand how it would happen.
Calls for investigation, huh?:scratch

Well, don't I feel silly. I didn't know my tank was supposed to have a drain hose. Good thing I'm careful on fill ups. Any tips on the correct routing for the hose?

Run it through the air filter clips on right side and then around the swingarm pivot.

I'm pretty sure my gas overflow goes right back into the tank.

Unless you have an '85-on tank, you're mistaken.

Right you are! I went out and looked again. The tube goes through the tank and I mistakenly assumed it drained into it. I found the outlet nipple--right above the air intake. I must have knocked the hose loose when I took the coarse #3 steel wool out of the intake to take my ride the other day!
While we're talking--I got in a hurry and forgot to take the steel wool out a few weeks ago. When I got home one side had the steel wool still in and the other didn't. I am assuming if it is in the air box it will not hurt anything. Is that a correct assumption?
And another thing--when I got the bike there was a neoprene gasket around the gas tank filler tube. It was in pieces so I tossed it. I don't see that gasket on any parts breakdown and can't see what it is good for anyways. Unless it would slow the gas flow if the bike is horizontal.
Thanks for the feedback. :blah

It ought to be just sitting on top of the filter element.

Only "gasket" on fuel tank top I'm aware of is a plastic ring around the gas cap. It's there to keep water out and generally to improve the looks by covering the overflow trough (moat?).

This tank "breathes" through the cap--if you put a piece of saran wrap or similar over it, the motor will soon stop running due to fuel starvation. Sometimes a tank bag will do it.

A few years ago while running north up the New York Intersstate my /7 shuddered and quit. Don't know how I had the common sense, not as common with me as I'd like, to lift the tank bag with a towel to unblock the vent. Ran like a charm from then on.
