Fuel Pumps
A fuel pump is an essential component of a vehicle's fuel system. It is responsible for supplying fuel from the fuel tank to the engine. The fuel pump operates by creating suction that draws fuel from the tank and delivers it to the engine through fuel lines. There are two types of fuel pumps: electric fuel pumps and mechanical fuel pumps.
Electric fuel pumps are found in most modern cars and are located inside the fuel tank, submerged in fuel. A typical electric fuel pump consists of an electric motor that drives a fuel pump plunger or impeller, which creates suction that draws fuel from the tank and delivers it to the engine. The electric fuel pump is controlled by the vehicle's computer, which regulates the flow of fuel according to the engine's needs.
Mechanical fuel pumps were commonly used in older vehicles and are still used in some diesel engines. A mechanical fuel pump is driven by the engine's camshaft and uses a diaphragm to create suction that draws fuel from the tank and delivers it to the engine.
Regardless of the type of fuel pump, it is important to keep it well-maintained to ensure proper fuel delivery to the engine. If the fuel pump fails, the engine may not start or may stall while driving. Common signs of a failing fuel pump include whining from the fuel tank, difficulty starting the engine, and loss of engine power. If you suspect a problem with your fuel pump, it's best to have it inspected and repaired by a qualified mechanic.
