Strange liquid

I have a '77 Honda CB550. The vent next to the fuel cap has been recently making a gargling sound and spewing a light-brown liquid from it. I've tried draining the hose line attached to the vent opening, but the noises and liquid still continue. What is happening? And how do I resolve it?
Thanks in advance,

Rust mixed with gas perhaps?
