These two black pipes definitely look as though they should be connected but currently aren't. The two nipples are from the fuel tank and the hose exits under the bike. Can anyone reaffirm my suspicions please?

I believe those hoses get connected to those nipples. Overflow hoses

Cheers - found this diagram that confirms they should attach to the nipples.
