What are these? Are they supposed to connect to something?

I just got under my bike for the first time to do an oil change and noticed these 2 tubes just sort of hanging there.
Are they supposed to connect to something or are they just like air tubes or something?

looks like breather tubes from the carbs, its where the carbs drain once the bowls are full. move them up and down and see if they move on the back of the carbs.

Hi,

I would think that one of those is the overflow drain from the fuel gauge send unit and the other is an overflow from the battery. Or maybe a the drain hose from your airbox.

What kind of bike do you have? Is there a service manual or owner's manual on my website?


Thank you for your indulgence,

it is a 1980 gs550e i took a look at the service manual on your site but couldnt quite pinpoint what they were since there are a few other tubes near there.
the bike is running fine without them so i assume it isnt the fuel tube haha
so i was hoping it was just a breather tube like you said

Don't worry about them. At least one of them is a breather tube from the gas tank. Another is probably overflow from the carbs, or from the battery.

Simple enough to trace the tubes up to where they attach no?

[okiedokieiguess]

i trace them back and see what they connect to but i dont know what the part it connects to is and even if i did it wouldnt really tell me what its supposed to do. i am mechanically challenged haha

[tlepac]

So maybe trace them back and then get a good picture of where they connect and probably someone on the site can help

I agree with ddaniels' post. If you are not leaking anything and bike is running as it should then don't worry about them. They appear to be over flow tubes.

Just to hazard a guess here. I believe one is a breather for the tank (it would terminate on the inside exterior of the tank). And the other seems as though it could be a very long breather for the battery. Easiest way to see if that tube is on the battery is just to remove your battery.

The bike has the following "open" tubes:

- Two vents for the carbs, usually these hoses lay on top of the airbox
- Airbox drain
- Battery breather/overflow tube

On bikes with a fuel sensor unit Suzuki has a leak containment feature so if the sending unit seal leaks the fuel will collect in a funnel like contraption over the sender unit and send the fuel down to the ground.

Bottom line: don't worry about those tubes and make sure they are not in-line with the rear tire in case the bike starts to spew fluids.

Oh yeah, forgot about the airbox drain hose.

ive never seen a breather tube for the tank before, depending on how many carbs you have its probably for the airbox and carbs. battery breather tubes are usually clear vinyl not rubber

It's not actually a "breather" tube. It's more like a drain hose. It's there if the fuel gauge send unit ever springs a leak. If you have no gas gauge on your bike you don't have to worry about it.

... depending on how many carbs you have its probably for the airbox and carbs.

The CV carbs do not have drain hoses like the VM carbs. The CV carbs do have vent hoses which usually lay over the back of the airbox but don't go all the way down under the frame.

... battery breather tubes are usually clear vinyl not rubber

The drain hose on my old battery is rubber. I left it in place even though my new AGM battery does not have a drain. Who knows? I might have to put a wet cell battery in there in an emergency.
