What is a Mechanical Fuel Pump?

A mechanical fuel pump is a device that delivers fuel to the engine. Due to the fact that mechanical fuel pumps generally work best on carbureted engines, 

A carburetor squats over the engine and delivers fuel into the combustion chambers via intake ports. Some  ran the fuel lines below the gas tank so that gravitydoes the work of carrying gasoline from the tank to the carburetor. However, many models needed a little additional help to get the fuel from the tank to the carburetor. The mechanical fuel pump, which was usually located on the side of the engine, was therefore designed to run off of the engine’s momentum and provide the carburetor with a steady supply of fuel.

A mechanical fuel pump mounts to the side of the engine. A lever or push rod on the pump passes through an opening in the side of the engine and lines up with a special lobe on the camshaft. As the camshaft turns, the lobe moves the lever up and down, raising and lowering a flexible diaphragm inside the pump. With the motion of the diaphragm, gasoline is drawn down the fuel lines and into the pump. From there, the gasoline is pushed into the carburetor, which uses the vacuum of the engine to pull fuel into the combustion chambers.
