Ok, so it comes from under the plenium with around a 3/4" bore hose then reduces to a tiny 3mm hose as it follows down the intake pipe then finishes, disconnected, back to a 3/4" hose down near the radiator on the intake side of the stock intercooler.
Ill take a photo tomorrow if no-one knows what im talking about:Giggle

After searching through other peoples pics on the various rotary forums i think its from the airpump.
