1981 750 honda c vacuum hose routing

[G PLANT]

         Will someone please show me the correct vacuum routing for a 1981 Honda custom?

I would check the manual section here. Even if it does not show routing there might be some pictures that show it.

Tools I got this from bike bandit. Hope this helps ! I threw the thing that looks like a octopus in
the trash. This works like a fuel pump but does not work half the time, and has been known to fail, and not deliver enough gas when needed. They put this on so fuel would not have to be shut off every time you stop. I just run gas line from fuel tank to large nipple behind carb 2 ,and the small nipple on carb 2  cut short peice of hose and plug up with bolt. there is a small nipple between 2, and 3 or center of the 4 carbs
this is the vent hose,put on and just feed down in between carb rack , and air box. If this does not make sense let me know.You will have to shut the gas petcok when stopping if you eliminate the fuel pump.
 All this talk of nipples kind of got me excited !!!!!!! have to go.

Hey Krammit, (nice name!) I have an 82 cb750c I am trying to get running correctly. I think it has something to do with vacum/fuel lines. Mine did not have that auto shut-off when I got it. I saw your diagram and now have some hope. Please give me some more info on how to make this work. Some has told me to run vacum lines (10mm or 3/8s) from a nipple located behind or near to the oil cap. up to a tee on top of air box and down on the other side under carbs. I have the fuel line or tee between carbs 2 and 3 and not sure where it goes...I'm told it is an overflow. ...when I have the bike running (with choke) it kinda runs ok...but if i go no choke..it dies ...however..if i apply air to that so called overflow ..the engine revs.
hope you can help me get this running properly.thanks
