What is the mechanism that pumps fuel from the gas tank to the engine?
1. FUEL PUMP . A fuel pump is a mechanism that is in charge of pumping fuel from the gas tank to the engine. It’s a direct current electric motor connected to an impeller in one housing. Once it’s given electric input, the motor turns the impeller and it starts pushing fuel. This is an explanation in a nutshell.
What does it mean when the fuel pump is working?
