The main responsibility of the a fuel pump is to provide an even flow of fuel from the gas tank into the engine at an optimal pressure for ideal combustion. Fuel pumps on vehicles usually function within a specific pressure scale, anywhere between 30-80 psi, an important detail because if there is not enough pressure the engine can very well sputter out or stall. This fuel delivery is precisely regulated to enable the engine to deliver smooth and efficient performance under a wide range of driving conditions, helping to balance performance output and fuel economy.
Electric fuel pumps are standard equipment on late model vehicles and most run continuously as long as the engine is running delivering fuel when called for. Fuel injection systems especially need a consistent fuel stream, as pressure spiking can disturb the precise air/fuel mixture required to combust effectively. This contributes to better fuel consumption and the role of the pump itself affects miles per gallon (MPG. Industry estimates suggest a well-operating fuel pump can increase gas mileage by as much as 10%, which results in overall savings for the driver.
This is the job of a fuel pump's internal parts -- such as the motor, impeller and pressure relief valve. The impellers suck fuel into the pump and force it toward the injectors, with a pressure relief valve preventing over- pressurization to protect both pump and engine. Fuel Bottle Failure of any one of these $300-to-$1,000 repairs will stop up fuel fire.
The way the tank is placed also affects how the pump is cooled, which requires it to be surrounded by fuel in order to avoid overheating. Having enough gas (1/4 tank minimum) helps to keep the pump cool since running an empty tank increases the chances of overheating, which might results in a damaged and short-lived fuel pump. In fact, results of tests showed that use of a fuel pump without an adequate supply can decrease it by up to 30% in life expectancy.
” Efficient fuel delivery is vital to engine health, says Dan Harper at Mike Shaw Buick GMC in Denver: ” If an air-fuel mixture is too lean (a lot of air compared with the fuel), your engine could blow up without the cooling effect of adequate gasoline on hand. Harper says that operating on low fuel and missed services disrupts pump performance as well and can leave permanent damage.
