The firewall that is run through the same grommet that both coolant to heater core hoses run through as well. It's about a 1/4" hose with a 90 degree nipple on the top end. It's not connected to anything and I was wondering if it should be? It looks like it should be attached to the brake master cylinder. Thanks.

This thread needs pics. But yeah, sounds like the vacuum line to the brake booster.

Ok I'll snap some when I get home. It's not the brake booster. It's a clear/yellowish line.

Clear yellowish? Battery vent?
