Fuel Pump Assembly Replacement
Fuel Pump OverviewThe fuel pump is used to supply fuel to the fuel injection system or carburetor of your vehicle. Older vehicles use a mechanical pump to deliver low-pressure fuel to the carburetor, while fuel-injected vehicles require an electric pump capable of generating the high pressure required to make the system work efficiently. A fuel injection system is more efficient than its predecessor the carburetor and can better operate in extreme conditions while becoming more dependable at startup.
In simpler terms, the purpose of a fuel pump is to draw fuel from the gas tank and deliver it to the fuel injector or carburetor. All vehicle engines operate by way of a mechanical pump (Carburetor) or a fuel-injected pump (Fuel Injected). Chances are if your engine requires a mechanical pump it is quite old and has fuel pumping at low pressure from a fuel tank to the carburetor. If your vehicle is newer most likely your engine uses a fuel-injected pump as do most modern engines and transfers fuel at high pressure into the fuel injection system from an electrical pump mounted either inside or inline with the gas tank.
