How A Fuel Pump Works?

Working Of A Car Fuel Pump

Helpful Information
A fuel injection system is more efficient than its predecessor, the carburetor, and can better operate in extreme conditions. Electric fuel pumps can experience wear and tear on the armature, brushes or bearings, which causes a gradual loss of pressure. An inlet filter sock is designed to block tank sediments. Running the fuel pump out of gas can cause premature failure.

Step by step explanation on how an automotive fuel pump works. This article pertains to most fuel injected vehicles.
Step 1
 - A fuel pump starts by being submerged inside of a fuel tank which is common among all fuel injected vehicles. The sump holds fuel near the pump inlet.

Step 4
 - Sometimes held in by clips the fuel pump can by mounted to the top plate and be serviced as a unit.
