Can someone identify what is up in this pic?

[mpeter5]

I changed over from an oil injection to a premix on my '92 2-stroke. But, I have no idea what this line does, or if the two ends were connected, and if so, by what.
I apologize, but this project sat for awhile, and I don't recall leaving two open-ended hoses that weren't there already. Obviously, the free line and the other line running to the fuel filter are both coming from the fuel pump to the left. I haven't dug into the fuel pump as it was running fine before changing to a pre-mix.

Any help, (sccowboy) greatly appreciated!
Thanks
