Low Pressure Pumps

A low-pressure gasoline pump is a component of a fuel system in vehicles, designed to deliver fuel from the gas tank to the engine with lower pressure compared to high-pressure fuel pumps typically found in direct injection systems. These pumps are often used in vehicles equipped with carburetors or port fuel injection systems. They operate at pressures typically ranging from 4 to 10 psi (pounds per square inch), which is sufficient to supply fuel to the engine’s intake manifold. Low-pressure gasoline pumps are generally electrically powered and are located inside or near the fuel tank. Their primary function is to ensure a steady flow of fuel to the engine, maintaining proper fuel-air mixture ratios for combustion.
