What line is missing under the throttle body (Page 1/1)

Can anyone tell me what line that looks like a brake line is on the left and does it wrap around to a different fitting in the front of the throttle body?

Looks like a throttle body coolant line. The one on the trunk side of the TB is also missing so it may be blocked off. The only reason for these is to prevent the TB from icing up in cold climates. Many people removed them.

Yes, missing Coolant Lines... ⚠️ Warning:"Carburetor Icing" doesn't happen only in "Cold Climates..." Can happen when weather is warm to barely cool and air have enough moisture.
Air cools fast going thru small openings via "Venturi Effect" like throttle close or in IAC bypath air and freeze in TB and TBI units.
Yes, Many remove the lines claiming makes the car faster but then take a gamble if have freezing problems... When it happens, often have No Warning and hope only the engine dies. Can freeze sometimes w/ throttle open and you can't slow down and hit something or worse someone.
I had this problem w/ a van that was missing "Thermac pipe" that use exhaust manifold to heat air... Would die @ a stop light after running a bit @ highway speeds sim to Infamous TCC problems GM had w/ TH125c and others transmissions. Fortunately freezing would melt nearly fast too so could start the van quick to get off the road and find out what happen and missing pipe. (Exhaust Heat Cycling and "water" will make rust problems for this system no matter what name a company calls them.)
