There is a vacuum hose that comes off the bottom of the second tee above my right fender and goes to the back of my engine behind my distributor cap. I can't see where it goes. Can anyone tell me? I have a 98 Blazer.

 

is it the nipple on the inside of the driver fender it popped off? its tucked underneath some stuff but its there.

 

It sounds like it could be the window washer fluid; this runs to the same area as another hose that is a vaccum that connects to the 'T' which connects with a vaccum hose coming from the passenger.
