fuel leak

[Roadog]

 1998 Tourer , I always run non-ethanol fuel and never had a fuel issue of any kind. 40,000 miles , I bought it new . All the carbs are dry and the fuel is running out of a rubber line the size of a fuel line just to the rear of the rear stay bracket , this tube has an elbow  and the fuel is running out of this rubber line.  It stops instantly when I turn off the manual Pingel petcock . It really looks like a fuel feed line ,it is next to the drain lines . There is no fuel getting to the even side (2-6) carbs but it tries to start on odd side only . If I knew what this 'tube' is I could decide on how to proceed.  It was started about a month  and a half months ago. I have a factory shop service manual but it didn't help with locating or identifying  this tube where the fuel is pouring out,  I might have to pull the tank and air box to get a better look . Any insight you can give is much appreciated .

Tank vent?

Pulling the tank is no big deal, but it's easier without a full tank.

And a full tank is better for winter sitting.

When putting tank back on, the neat trick is a small piece of 2X4 or fir strip on end, under the rear of the tank (and the frame) gives you just enough room to hook the lines back up (and lets you use both hands).

The interstate also has a fuel sending unit for the fuel gauge that has to be plugged back in.

Sounds like the fuel rail o-rings to me. Sometimes after fuel has wettened (sp.) them, they will quit leaking. Might take overnight though.

There is a carb vent hose that terminates at the rear of the carb bank bracket.  I think think a stuck needle valve or stuck float can cause this. Try tapping in each carb bowl on the side with the leak. If you can’t get it stopped you will have to remove and rebuild the carbs.

 Thank you everyone who posted a comment, I am sure the problem is a float issue, allowing raw fuel to pour out of the overflow tube, either one or more are stuck open or they have failed  to seal properly.  I will pull the tank and use my auxiliary fuel cell to test . I will post results of what I find . Thank you all !
