    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

We should be seeing a fuel petcock somewhere there on bottom of the tank.
THe vacuum line is the smaller of the two goes on the smaller of the two on the petcock.
The larger is the fuel line.
Unless it is the drain line for the fuel guage sender. (I think the 650 has such. but 650 is the model with the most difference from all the others.)
 
Hard to tell from your photo. Fuel line is middle of carb rack. There are two vent hoses.
try this photo

The answer to “do the carbs need cleaned?” is nearly always YES, especially if you have a rusty tank.
BS(CV) carb cleaning /. Rebuilding tutorial (this one by Ed Ness) and a lot more info found on BikeCliffs Website.
bigger hose is fuel, smaller one is vacuum. The corresponding nipples on the petcock are sized accordingly.
