Change vacuum due to overboosting problems

Hello..

I need to change my vacuum hoses due to overboosting problems. I've read that I have to begin with this.

My "problem" is that i want to buy these tubes from US, but I don't know which lenght I need.

I found this on a forum:

A3 Jetta: 3 foot of blue/red. 12 foot black 3mm. 5 foot black 4mm

B4 Passat: 6 foot red/blue. 15 foot black 3mm. 5 foot black 4mm

A4 B/G/J: 10 foot of black 3 mm. 5 foot black 4mm.

I have a Skoda Supber 1.9 TDi 2004 modell.

Anybody that can help me?
