vf500 fuel tank

Hi i was wondering if anybody knew if there is a vacuum hose to go to the fuel shutoff valve or if it just a fuel line on an 86 VF500f. I know theres no fuel pump but im not sure if theres anyother lines going to the shutoff valve.

 

There is a vacuum hose, but I believe that it connects to the outside of the carbs on the left side. When I last had my tank off, I'm pretty sure that there was just a single fuel line from the shutoff valve. I can double check things if necessary. Let me know.

 

Thanks a lot, ill check probably tomorrow about that vaccum line, the double check would be appreciated, thanks for all your help.

 

OK, I checked my bike as well as the service manual and there is a single fuel line to the shutoff valve. There is also a single vacuum line that runs from the left side cylinder intake to the diaphragm. The diaphragm is on the back of the shutoff valve, so there are two lines total.

 

Thanks a lot found it right away, dont know how i missed it.
