Why does my nitro rc car have to lines line leading to the fuel injector and one leading through the exhaust?

You mean the line from the exhaust to the fuel tank? That one is to pressurize the tank, to avoid an underpressure in the tank which would stop the fuel from flowing to the carburator.
R/C engines (and fuel systems) are rather primitive...
