vacuum leak or fuel problem???

2005 vulcan vn 750; moved tank to install new coolant hose. 2 hoses apparently disconnected; (1) is from underseat emmissions-not sure where this connects. The other appears to be from (R) of left side carb, could someone explain where these connect??? Bike was running fine before moving gas tank, now will not start. Siphoned tank before moving and replaced some fuel, tank still unbolted and (R) side air-cleaner is removed... What could possibly be the problem? Bike cranks over fine; however acts like not getting fuel. Would apprecite any advice.... Thanks

petcock is vacuum controlled.

vacuum hose from left carb goes to petcock. fuel will not flow unless vacuum is present. The center hole on the petcock is the vaccum line in question.
