I took my tank off for the first time after buying this bike last May.. (2003 DL1000)

Just noticed this hose next to the right side of the rear throttle body. (as seen in photo below)...It just runs down the right side of the engine and stops at the bottom of the frame and is open there also (like it is supposed to be a drain for something)

Anyone have any idea where (if anywhere) this hose is supposed to connect to?

Thanks

Do you have the service manual?

It's almost certainly the drain line from the fuel filler cap well. A metal tube runs from the fuel cap well through the fuel tank and exits the bottom. A rubber hose connects to the tube end and takes any rain water or fuel overfill from the well and transfers it to the ground without spilling in over the engine.

Thanks,...that makes sense....I just didn't notice it when I disconnected the fuel line and fuel pump wiring....It must have popped off when I lifted the tank out.....a wealth of information on this forum

Greg,

I had the same question this weekend about a hose I found on my DL650 after re-installing my tank after having it off the past two months. I didn't remember where it came from. Greywolf suggested I try putting water into the filler cap well (be careful that water doesn't go into the tank!) as a test. When I did that, water came spilling out over the engine in a diffuse way. Since that can't be the design (having gasoline spill all over everything would not be a good thing), I'm sure there must be a place for this hose to go so that any overspill gets diverted down to the ground. When I have time to lift the tank again (yes, I put it back on w/o making sure where the hose goes :headbang:), I'm going to try the water-in-the-filler-well test again before completely removing the tank. Hopefully that will show me where the water is spilling out. And that hopefully will show where this hose should go. That's the plan, anyway.
