Fuel pump
Fuel pumps are less common on two-wheelers with carburetors, but they are mandatory on fuel-injected engines.
If the tank is lower than the carburetor (as is the case with some scooters), it is not possible to feed the fuel to the carburetor by simple vacuum. In this case, a pump takes over the job, so it must always be in working order.
If your vehicle does not have a fuel pump and the fuel does not reach the carburetor, you should check the fuel tap and the hoses.
