Hi all I’m just after advice I took fuel tank off today I disconnected the fuel pipe and on the vacum on right side it had one small pipe on it I disconnected that two and when putting tank back on the bike I realised that there looks like there should be another small pipe connected to the vacum but there isn’t one on my bike going to it so I’m not sure if there should be one or if it’s a release or something any Info be great

There's only one vacuum pipe that connects to the fuel tap.

the middle one is the drain, the outer the vacuum

Thanks guys
