Rear of carburetor leak

That is not a carburetor, it is a throttle body. There should be no gasoline that flows through the throttle body, just incoming air. The gas leak is most likely associated with the fuel line to the fuel injector rail or the fuel injectors.
The best thing to do is remove as much as you can to gain access to the entire area around the leak and without starting the engine just turn the key to run and run the fuel pump for two seconds and try to locate and pinpoint the fuel leak and fix it and recheck it before starting the engine and allowing it to heat up.
