You can get the silicon hose from Demon Tweeks for about £8 for a 3 metre length that will be more than enough for the Aero. Make sure you ring them and talk to an assistant about it, rather than ordering on-line, because they sell colours not listed in the catalogue, and will post royal mail first class instead of courier if you ask them.

The vacuum hoses take the pressure from the inlet manifold and distribute it to various sensors and the boost gauge on the instrument panel. One takes pressure to the fuel pressure regulator for instance, another to the 'dump' valve.
They deteriorate due to the heat/oils etc underbonnet and harden until eventually they crack or break off completely.
Depending on which breaks and where, various symptoms might occour, for instance lack of indicated vacuum on the gauge etc.
