The electric fuel pump is used in modern internal combustion engines to provide fuel in the gas tank to the injectors. The pump must deliver fuel under high pressure, so the nozzle can spray it in the engine.
For the correct engine performance, fuel pressure should be within allowed specifications for any given engine. Too low-pressure can lead to “fuel starvation” engine misfire, excessive vibration or stop the engine under load. Too much pressure causes irregular engine running too rich mix, and excessive contamination.

Installation Of Electric Fuel Pump
- Electric fuel pumps are often installed in fuel tank (ingestion ), even though some can be set up outside. Some cars may be equipped with two pumps (one pump in the tank and the main pump on the outside).
- The positioning of the pump in the gas tank helps mute the buzzing sound of pump’s electric engine. Submersion into the gas helps lubricate and cool the pump’s engine.
- Driving with fuel tank full of less than 1/4 of its quantity can shorten the life span of the pump and trigger rapid overheating. Additionally, it increases risk of pump left with no gasoline during rapid acceleration or deceleration.
The pump is usually a part of a module which also contains a float which carries electrical signals to the level indicator, located on the dashboard. If the fuel pump needs replacing, it may be replaced individually or the entire module assembly (it’s expensive, but much simpler).
