Best Answer

When your engine takes in gas, it only takes in a certain amount depending how hard the engine is being pushed, the fuel pump constantly pushes the same amount of fuel so something is needed to regulate how much fuel is going to go into the engine, the unused fuel goes through the return line back to the fuel tank.
