There are two significant types of fuel pumps: Exhaust gases can lead to improper lubrication and cooling of the electric fuel pumps and can damage the pump. It can increase acceleration, braking, and sharp turns which also increase the risk of temporary starvation of the pumps for fuel. If the fuel pressure is too high, the engine will not run properly, fuel will be wasted, and contamination will have appeared in the fuel.ĭriving with a fuel tank with less than 0.25 fuel will overheat your engine and reduce the pump’s life. If the pressure is too low, the engine will run out of fuel, causing the engine to stall, hesitate, misfire, or lean. The pressure of the fuel must be according to the requirements for the engine to operate normally. According to the use, these pumps must supply fuel at high pressure (typically 30-85psi) for the fuel injector to inject fuel inside the engine. The carbureted engine generally uses a low-pressure mechanical pump located outside of the fuel tank, while a fuel injector engine generally uses an electric fuel pump.Įlectric fuel pumps use in engines that are equipped with a fuel injector to transfer fuel from the fuel tank to the fuel injector. Whether you’re trying to breathe new life into a large piece of carbureted block or running a lawn device, the engine requires a stable fuel delivery, which is the purpose of the fuel pumps. This is because the fuel supply is important to keep the engine running. A fuel pump is an important part of the IC (Internal Combustion) engine. What is a Fuel Pump?Ī fuel pump is part of an automobile that supplies fuel from a fuel tank to the carburetor of an IC engine. This article explains the fuel pump working, types, and applications. The efficient working of the fuel pump ensures the proper supply of fuel to the engine. The fuel pump is one of the most important parts of the fuel system.
