Electric Fuel Transfer Pump

The Fuel Pump in your car is usually the most important component in your car or some other type of internal combustion engined device. A lot of engines - like some older engines that go on motorcycles - are the type of engines that don't need a Fuel Pump.. at all. In most cases, carbureted engines use low pressure mechanical pumps that are typically mounted to outside of the actual fuel tank. Fuel Injected Engines a lot of the times use an electric Fuel Pump - this is mounted on the inside of the fuel tank.
Before everyone started getting crazy about Electronic Fuel Injection, most of the carbureted car engines used a mechanical Fuel Pump to transfer fuel from the actual Fuel Tank into the fuel blows of the installed carburetor. Mostly all of the mechanical fuel pumps are known as something called diaphragm pumps. These pumps are a type of positive displacement pump.Electric Fuel Transfer Pump

Diaphragm pumps have a pump chamber where the volume is either increased or decreased by the flexing of a diaphragm that just so happens to be.. flexible; it's most similar to the action of your typical piston pump. There's something called a check valve and it's located at both the inlet ports AND the outlet ports of the pump chamber. This is supposed to technically force the fuel to flow in one direction and one direction only.
One of the most common problems that you will likely encounter with Chevy pickups is fuel pump malfunctions. Over time, you will begin to notice a dramatic decrease on the truck's fuel mileage and engine performance. If that is the case, replacing the fuel pump might be necessary. With a little know-how and basic knowledge on automotives, you can easily accomplish the task.
If your fuel pump is not working efficiently, then you cannot expect your vehicle to run well. Every vehicle engine operates by using a mechanical pump or a fuel-injected pump which draws gas from the fuel tank and delivers it to the carburetor or fuel injector. Most modern engines use a fuel injected pump to transfer fuel at a high pressure via an electric pump into the fuel-injection system. If your engine is quite old it may use a mechanical pump to feed gas from the fuel tank to your carburetor.
