carb coolant lines plugs

[smegun]

ive got a 1st gen ls with the v8 im looking for a part number for the uppermanifold to carb coolant line i believe its a plug for the coolant line to run from the manifold to the carb
that is under the intake over the manifold i believe there is a plug that the line comes out of
it may be the line running to the carb heater on ls gen 1 not gen 2

I believe you are looking for the throttle body heater hose.

It might still be available through Ford... or maybe sombody like O'Reilly's/Advance/Napa or Autozone might have an aftermarket replacement.
