The basic components of a mechanical fuel pump for carbureted engines are: 1. Cap: The cap is the top part of the fuel pump that covers and protects the internal components. 2. Upper body: This is the main housing of the fuel pump, where the diaphragm and other components are located. 3. Diaphragm: The diaphragm is a flexible membrane that moves up and down to create suction and pump fuel from the tank to the carburetor. 4. Spring: The spring provides tension to the diaphragm, helping it return to its original position after each pump stroke. 5. Lower body: The lower body houses the inlet and outlet valves, which control the flow of fuel into and out of the pump. 6. Rocker arm: The rocker arm is connected to the camshaft or crankshaft of the engine and transfers the motion to the diaphragm, causing it to pump fuel. These components work together to deliver fuel from the tank to the carburetor, ensuring proper fuel supply for the engine's combustion process.
