The fuel pump is an essential component in the engine of a car as it transfers fuel under high pressure and volume from the tank to feed the engine to deliver peak performance. Modern fuel pumps are designed to operate within a specific range of 40-60 PSI (pounds per square inch) to ensure an optimal environment for fuel injection into the engine. And it's required to satisfy the engine for power and get close or meet manufacturers' MPG claims as well. In the case of a normal mid-size sedan, a 200 hp rated fuel pump is put in place where it can function properly and distribute consistent levels of fuel even when the vehicle is being driven at high speeds.
The higher requirement for precision in fuel delivery has made electric pumps popular due to their replacing older mechanical fuel pumps starting from around the 1980s historically. Older carbureted engines often made use of mechanical pumps, but electric has become a standard across fuel injection systems. This change enhanced the engine strength, notably in acceleration and gas utilisation, which resulted in 15 percent less gas used to more ancient systems. A prominent example from the auto industry is General Motors' introduction of electric fuel pumps in its vehicles in the late 1980s; which resulted in much better mileage across its fleet.
This quote attributed to Henry Ford explains a lot of the reason about why innovation in automotive technology is not all that common: "If I had asked people what they wanted, they would have said faster horses." Such innovation can be seen with the evolution of the fuel pump, in its case advances in materials and electronics has made them last longer. According to the same source, present-day fuel pumps are intended to last 100,000 – 150,000 miles—which will keep many flannel-wearers from a lifetime of misery. New fuel pumps, including installation, can come out to between $400 and $600 depending on the car. This is a big advantage for just about any car owner.
Consumers may need to diagnose engine problems based on the specifications of a fuel pump. In the case of a failing fuel pump, it may manifest in what feels like a sudden loss of power or no-start condition – both symptoms that can be confirmed by diagnostic equipment testing the pressure output at the pump. For example, Bosch is one of the largest manufacturers of automotive components in the world and they have fuel pumps available which remain 90% efficient over their operating life, a demanding specification for an earlier stage concept to match.
To sum this all up, a fuel pump is responsible for giving a car its life-blood, and as technology continues to improve it will provide people with the ability to keep their fuel system more reliable and also longer lasting. Visit Fuel Pump to read more information on a variety of fuel pump products
