How does an electric fuel pump work?

How important is an electric fuel pump in the operation of cars on modern roads — transportation designed to convey gasoline from a tank-powered plant where combustors are located with compression ignition and back? Typically electric fuel pumps operate within a pressure range of 30 to 85 PSI (pounds per square inch), sometimes with higher output given the larger engine need. It is responsible for delivering the right amount of fuel to each injector, which controls how smoothly your engine runs. Turbocharged or supercharged vehicles that require high fuel flow may experience operating pressures of 100 PSI, so the higher pressure ratings are relevant to specialized applications.

Itself typically being found inside of the fuel tank surrounded by fuel This not only helps keep the pump itself cool while in operation, but also reduces the chances of vapor lock—wherein some or all of a vehicle's fuel exits its liquid phase and becomes vaporous far too early in the system to be effective at maintaining constant fuel flow. Because the pump stays underwater, it helps to keep its temperature constant and this improves its life span. Typically an electric fuel pump should last 100,000 – 150,000 miles but running on low levels of the vehicle can cut that down by up to 20%.

An electric pump is a motor that drives an impeller or diaphragm via the fuel line. The pump sits in the tank and moves fuel out of it, using an electric motor that also provides cooling—it's where all your power goes—as well as to convey make-up fuel from swing-arm fairings en route to injectors. This all happens quickly, of course — pumps are programmed to move between 90-110 liters per hour (LPH) for typical passenger cars. High-performance cars, on the other hand may need fuel pumps that can supply as much 255 LPH if you want to be able feed higher power engines accordingly.

Electric fuel pumps are known for their capability to adjust the pressure of fuels, which is a major benefit. Controlled by the vehicle's ECU (Engine Control Unit), it is capable of modulating its output based on real-time engine demands. One such example would be under acceleration when the fuel flow should increase as compared to at idle -- however efficient and clean that operation might seem. This efficiency contributes to improvements in fuel economy and engine performance, which helps – especially when it comes to modern vehicles that are designed for high-efficiency standards (to assist with saving energy consumption).

Fortunately, for the more reliable and long-lasting electric fuel pumps that clogging is not too common as these failures are typically caused by other issues like poor maintenance of a vehicle causing electrical faults or running the pump dry due to an empty tank. According to Automotive News, almost 30% of electric fuel pump failures are due to bad gas or debris in the tank that tears up a high-dollar impeller on its way through. This pump is designed to last a long time, however there are things you can do like changing the fuel filter every 30k miles that will help avoid these problems.

The cost of replacing an electric fuel pump usually falls between $300 and $800, depending on the car's make & model. While pump failure is fairly common—Edmunds estimates that simply doing this will reduce the final repair costs by up to 40%.
