What is the fuel line routing for a primer bulb?

The fuel line routing for a primer bulb typically involves connecting the fuel line from the fuel tank to one side of the primer bulb, and then connecting another fuel line from the other side of the primer bulb to the carburetor. The primer bulb acts as a manual pump that helps to draw fuel from the tank into the carburetor to aid in starting the engine. It is important to ensure that the fuel lines are properly connected and free of any kinks or blockages to ensure proper fuel flow.
