For 2018, General Motors had fitted its performance vehicles with direct injection systems using Fuel Pumps capable of delivering fuel at pressures of over 2,000 PSI. It gives better fuel atomization to enable more efficient combustion for more power delivery with fewer emissions. Systems like these are proof that the advancement in fuel pump technology has been improved to meet both higher and diversified demands regarding performance and regulations.
The fuel pump systems also vary in their installation site. The In-tank ones, being submerged into the fuel, are more common for modern vehicles because the fuel cools the pump, adding to its life. If properly maintained, such pumps can even withstand distances of more than 100,000 miles. The External ones are usually applied in racing or high-performance uses where it is easier to access and replace them but are exposed to the external environment, hence requiring more frequent checks.
As stated by David Vizard, an automotive expert, "Fuel systems are the lifeline of any engine, and the right pump can make or break performance." Selection of Fuel Pump is done based on the power that the engine produces, the required fuel pressure, and the design configuration of the fuel delivery system.

How Do Fuel Pump Systems Vary?
The design of Fuel Pump systems is based on the type of engine, method of fuel delivery, and demands for vehicle performance. The two major types are the Mechanical Fuel Pumps-very commonly used in the older vehicles with carbureted engines-and Electric Fuel Pumps, which come installed by default in modern fuel-injected cars. Mechanical pumps operate under lower pressures, usually up to 4 to 6 PSI, which is quite enough for carburetors. On the other hand, electric fuel pumps run on much higher pressures around the range of 40 to 60 PSI to cater to fuel injection systems that need more precise fuel delivery.
In particular, high-performance vehicles featuring turbocharged or supercharged engines call for a more powerful Fuel Pump that is capable of delivering more than 100 PSI. A typical example could be after-sales high-flow fuel pumps such as the Walbro 450 LPH that have been designed to support over 600 horsepower on an engine. These kinds of pumps make sure that the capability of the fuel system to provide adequate fuel at higher pressures and flow rates prevents fuel starvation at high-load conditions.
