Fuel starve

Hi
My Car is a 68 barracuda powered by a 340ci
I replaced the fuel pump And have a rebuilt carb but still face the problem of not getting fuel when engine runs at idle speed once hot ( typicaly ok when starting cold but then Starving when hot )
No issue when engine runs above 1200rpm

other Point is that i also get the carb dry when car is stopped For 30mn after running and engine is at running temp

could it be due to some issue on my fuel line ? Other ?

thanks for your support

You want your fuel filter and gas line to carburetor set up like in this picture, keeping the gas line and filter away from the hot cylinder head.

And do not want the fuel filter horizontal up on the intake manifold area either.
