Hose Problem

I just bought a 81 kz550 and am in the middle of fixing it up but ran into the problem that a have two small lines ( they appear to be vacume lines as they come out of area of the carb where the slide goes up and down and two larger hoses which appear to be fuel lines. The petcock is stock and im confused on where all these hoses go. Ill try to get some pics up tomarrow. If some on could help me or suggest a repair manual with detailed diagrams i could really use the help.

Is it a vacuum operated petcock? I think I know what two lines you are talking about, and I don't even have them hooked to anything... What are those? I don't think they are vacuum..

yes im preaty sure its a vacuum petcock heres a picture

Okay I had to go look at one of my 550's to get this figured out. Starting from the top of your pic, the first hose you have outlined in green is the vent hose and does not connect to anything just route it over the airbox somewhere. The second hose between carb #2 and #3 that you have outlined in red is the fuel inlet, this gets connected to the larger of the 2 outlets on your petcock. The third hose that you have circled in red is a vacuum hose that connects to the smaller outlet on the petcock. The fourth hose you have circled in green is the vent hose for the #3 and #4 carbs again it connects to nothing just run over the airbox just like the first hose.

Thank you very much you have made my life a lot easier
