- You have fuel in your tank and a fuel pump in your tank (or it could be up under the hood) and the pump pushes the fuel through the fuel line into the carburetors/injectors (figure A). The unburned fuel will go back to the tank through a fuel return line (figure B).
- On an older style vehicle, the fuel pump draws the fuel up from the tank and has a lever (figure C) that is operated through the camshaft in the motor; it then goes through a fuel filter and into the carburetor where you have the air/fuel mixture.
- Newer vehicles push the fuel from the tank with an electric pump (figure D) that is submerged in the tank and keeps constant pressure in the fuel in order to provide pressure you need for fuel injection.
- Injectors provide an atomization of the liquid. It uses individual injectors for each cylinder (figure E), unless it is a throttle body injector in which case one injector or two injectors work right where the carburetor used to be. The fuel injector is a small spray nozzle that is electrically controlled -- an electromagnet opens and closes to keep the fuel atomizing perfectly so that it gives you fuel efficiency, horsepower, and the extra reliability that fuel injection provides over carburetors.
