'93 Prostar with an LT-1

My fuel tank gauge is not working right, I noticed a green wire not attached to anything.
Anyone know where this goes?

The red and black are connected to the sending unit at the top of the tank.

This might explain why it is not connected. I believe the other end goes to the filler neck. The lose end was connected to my fuel pump housing thru a couple of harness connections.

chances are the magnets have come off on the cork float

and the wire is probably meant to go to the filler, I just had mine out and I think that it is green
