Couldn't be easier. Buy some vac hose - the silicone stuff from the usual Saab specialist parts suppliers (PartsForSaabs in the UK, EEuroParts in the US) is what you want - 3mm internal diameter, about 5m length will be _more_ than enough. Then all you need to do is go round the engine bay disconnecting one old pipe, cutting a similar length of new, and plugging it back on. Do one at a time, so you know what's connected to what...
