Hey guys, I installed my new 92/92 combo last night. There's a vacuum line in the rear of the compartment that doesn't seem to go anywhere on the 92 intake. Anybody got any ideas?

Actually I can't, there's one from the drivers side that has 2 nozzles on it but only one line coming from it that goes to the rear of the intake, the other nozzle has nothing on it?. There's also one from the passenger side, just a single line, does this one plug into the one that physically goes to the intake? Do you have pics of the rear installed intake? Any help would be greatly appreciated!!

I just installed a Fast 92 on my LS2 vette, the vac line at the right rear should be the MAP sensor on LS1 motors, it is not used on the LS2:D

Yea there are only 2 vac ports on back of manifold. Larger one for brake booster and the smaller one on opposite side for AIR injection valve, I think thats what the smaller on is for...
