What is the difference between mechanical and electrical fuel pump?
The biggest difference between the two pumps is that mechanical ones usually depend on moving parts to pull fuel out of the tank and into the engine, whereas electrical ones use electricity and computer power to push fuel to the engine. Completely running out of fuel in a car with an electrical pump may cause damage.
Why do electric fuel pumps not explode?
The reason electric, tank- mounted fuel pumps do not cause explosions is that the concentration of fuel vapors is too high to allow an explosive mixture. Even if you completely empty a tank, open its access ports, and allow it to sit open, the concentration of vapors INSIDE the tank will still be too high to explode.
