Vacuum Line Diagram: A Closer Look
The vacuum line diagram for the GY6 150cc carburetor is a relatively simple one. It consists of three main vacuum lines: the intake manifold vacuum line, the fuel pump vacuum line, and the crankcase breather line.
The intake manifold vacuum line is connected to the intake manifold of the engine. This line provides vacuum to the carburetor, which is necessary for the carburetor to draw fuel from the fuel tank. The fuel pump vacuum line is connected to the fuel pump. This line provides vacuum to the fuel pump, which helps to draw fuel from the fuel tank and deliver it to the carburetor.
The crankcase breather line is connected to the crankcase of the engine. This line helps to remove excess pressure from the crankcase, which can help to prevent engine damage.
