On most vehicles, the fuel pump is an essential component that delivers fuel to the engine either mechanically or electronically. Cars manufactured before 1980 generally employ a mechanical pump that feeds the carburetor, relying on suction to draw fuel into the airstream. However, the popularization of fuel injection systems in the 80s replaced mechanical fuel pump systems by using a process of atomization to deliver fuel directly to the engine electronically, negating the need for a carburetor.
In most cases, carbureted engines use mechanical pumps usually located on the engine block or head. These are low pressure units that use positive displacement from a diaphragm pump to increase or decrease the size of a pump chamber. A check valve is placed at both the inlet and outlet to ensure that fuel flows in one direction only.
Modern engines now use more efficient electronic fuel injection systems that are located within the fuel tank. The fuel pump creates positive pressure in the fuel lines which then forces the fuel into the engine. Most modern cars include some type of ECU (electronic control unit) that helps to control the fuel pump, in particular, shutting it off in case of collision.
The indications that you may have a problem with your fuel pump are many and varied. However, regular checks of the fuel pressure with a fuel pressure gauge should be undertaken to identify early warning signals and minimize the impact of any mechanical or electrical failures. Other warning signs of a failing fuel pump may include: engine sputtering; loss of power on acceleration; loss of power under stress; sudden increases in speed or “surging”; and finally, the vehicle will not start at all.
