2001 Bonneville Vacuum Lines

I just started having performance problems and noticed most vacuum hoses connectors are broken or completely off, can someone please help me to make sense of the vacuum hose diagram which is really confusing. Also, are the rubber connectors available separately or do they only come with the lines ?
Is there a center stand available for this bike and also a low grab bar for the back of the seat.
This bike only has 3,200 miles on it and is otherwise in great original shape.
If anyone has live pics or a video of the vacuum lines that would be really helpful.
Thank you kindly one and all
