Brent, I used a 4mm piece of brass rod drilled out to .7mm. I then stuffed into the end of the vacuum hose that goes to the throttle body at the canister purge valve end. The large hose that comes off the BOTTOM of the VW evap canister goes to the air duct and the top one goes to the purge valve. I made an adaptor for the intake manifold and screwed it into the place where the brake booster port used to live and that hose goes to the bottom of the purge valve. Hope the pictures help. The last pic shows how I stuffed the OEM Subi air duct in. I was going to use the one I sent you but the stock works very well even in a 2WD. Just tight. If you are interested I have some high res. pics of the entire engine bay (like 1 meg files!). Norm Hoffman
