I used about 3.5 meters of 3mm, and 1 meter of 5mm. This was enough for all vacuum lines including the one inside the ECU, but I don't think it includes the recirculation valve (for the cabin air, not EGR). I used silicone which is fairly stretchy, so my diameters may be slightly off.
Be very careful removing the blue hose to the wastegate actuator. It's hard to reach, even harder to see, and I broke the nipple off the actuator, then spent a while removing and repairing it.
