Hi All,

Just bought a 98 Hawk with 30k miles. Took off the tank to change air filter. Marked the two hoses and the ports on the fuel tap that they go to and the vacuum hose and port. Also the drain/overflow (not sure of the name) hose and the larger port on the tank itself. I did not remember seeing another (5th) hose anywere on the tank. But I have searched the archives and have seen a few people say there is another hose. Also looks like there is on the exploded view of parts from honda. In the picture I attached, I am pointing at a nipple that has fuel leaking out of it while the tank is upside down. Does this require a hose? if so, is it just a vent hose that I need to route down with the other? When I took off the tank there was not a hose connected to this port??? I am new at bikes and this has me very stressed out. Please help!
Thanks,
Ken

 

There are five tubes. The two fuel lines, one breather tube and one drain tube which attach to the bottom of the tank- one where your finger is pointing and the other directly below in the picture. The fifth tube is the vacuum line from ther rear cylinder manifold which attaches to the extreme rear left side of the petcock.

 

The diagram is on page 2-4 of the service manual. If you don't have one you can find the link with the forum search engine and download it for free.
