fuel regulator hose

can anyone give me some advice on which hose re-connects to the fuel regulator for a 02 S3? is it one of the hoses from the left side of the tank? the manual doesnt specify, only that one is a drain line and the other a vent-rollover valve. any help would be greatly appreciated. thanx,D

for what it is worth, on an 02, there is no hose that needs to be hooked up to the regulator. however, there is on some of the earlier 02's and on pre 02 triples.
