airbox vac line

[deano1978]

Just looking at my airbox and vac lines and notice theres a vac hose on top of the airbox,but no hose. Anybody else?

I assume the nipple on the air box is sealed and not open to the elements? If so, then don't worry about it. Some have these for different engines. Same air box will fit several models.
