About this document
How Fuel Pumps Operate in Cars by Felipe Andrés is a document available to read on EtoBox.
A fuel pump draws petrol from the tank through a pipe to the carburetor or inlet manifold where it is mixed with air and fed to the engine. Mechanical fuel pumps are driven by the camshaft or crankshaft, while electric pumps use a solenoid to pull a diaphragm and draw fuel into the pump chamber. The pump then expels the fuel through one-way valves to the carburetor. Both petrol and air are filtered before entering the carburetor to clean the fuel and air.
