Vacuum not giving fuel help!!
So I'm almost done with my bike project and she is ready to run, though for some reason the pet cock was not allowing any fuel to flow. The tank is just fine had it checked. So I had that pet cock rebuilt, and all. So I hooked it all up and tried to start her. Still no fuel is going to the carburetors. So I believe my vacuum that sucks and pushes the gas through to the carbs is not going. What do I do? Help.
