Steel lines and flexible hoses carry the fuel from the tank to the engine. The Fuel Lines connect all of the various Fuel System components.
Unless some severe and unusual conditions occur to cause a large amount of dirt to enter the gas tank, it is only necessary to replace the filter in the line. One inside the gas tank and one in a line to the fuel injectors or carburetor. When the filter clogs, the electric fuel pump works so hard to push past the filter, that it burns itself up. Fuel injectors are more susceptible to damage from dirt because of their close tolerances, but also fuel injected cars use electric fuel pumps. This is more true with fuel injection than with carbureted cars. The fuel filter is the key to a properly functioning fuel delivery system.
There are two types, mechanical fuel pumps (used in carburetors) and electronic fuel pumps (used in electronic fuel injection).
The fuel pump is used to pump the fuel from the fuel tank, via the fuel lines into the fuel injectors, which spray the fuel into the combustion chamber- in order to create combustion. The gas cap seals the fill hose and is used to ensure thatĪ) Gas does not spill out from the car, andī) that the fuel system remains pressurized correctly (in vehicles that use pressurized systems). This is the point where the Gasoline (or other fuel) is put into the vehicle. The Fuel Fill Hose is the main connector from the gas cap to the fuel tank.
