Just putting the UIM back onto the FD, I took photos before it came off as a reference to all the hoses I pulled off and they're relocation. I've put it all back together but I notice that the black vacume hose that goes from the purge control solenoid to the UIM is not attatched and there is nowhere under the UIM to put it ( all holes taken up with whats in the photos ) . So I 'm thinking it was never plugged in to begin with, The car is a single Turbo setup, extra fuel rail , greddy FPR , bigger fuel pump, surge tank...

will having this unplugged cause any problems?

 

Nope - the purge control is just for emissions. Really, you can just open air vent the system, preferably with a filter.
