Need help!

I recently purchased a boat with a 1990 70hp Evinrude. I am trying to find out where a certain fuel hose goes. Im including a picture, there was a hose on the brass fitting leading nowhere and fuel was just coming out. There is also this black nipple, does the hose connect from the brass to the black one? Thanks in advance!

I believe a wee hose goes from the brass nipple to a nipple on the bottom of the air box.-----Is that black nipple used to grease the shift linkage ?
