Mechanical fuel pumps deliver fuel to the engine through the carburetor by vacuum pressure, and they work off the momentum of the engine itself. The carburetor blends fuel with air so that it burns more quickly. The mechanical pump is bolted to the engine's cylinder head or engine block. Internal check valves restrict the flow of fuel to one direction and keep it from bleeding back out of the pump.
Electric Fuel Pumps

Mechanical fuel pumps are powered by another part of the vehicle like the engine. Electric fuel pumps are powered by electricity, which is usually produced from the alternator or drawn directly from the battery. Most modern fuel injected vehicles use electric fuel pumps.
