The Fuel Lines connect all of the various Fuel System components. Steel lines and flexible hoses carry the fuel from the tank to the engine. When servicing or replacing the steel lines, copper or aluminum must never be used. Steel lines must be replaced with steel. When replacing flexible rubber hoses, the proper hose must be used.
Where does the fuel go from the fuel pipe?
From the outlet the pipe runs to the fuel pump - either a mechanical one mounted on the engine , or an electric one which is often sited at the rear next to the tank, or submerged in it. The pump sends the fuel to the carburettor , but there are one or more filters on the way - often in unsuspected places that are difficult to reach.
What type of pipe is used for fuel line?
The flexible section of the piping is usually made of reinforced rubber hose , but sometimes clear, flexible plastic tube is used. The most usual type of connector for metal fuel pipes on modern cars is a short length of rubber hose fitting over the pipe ends and secured by two hose clips.

The most usual type of connector for metal fuel pipes on modern cars is a short length of rubber hose fitting over the pipe ends and secured by two hose clips. Sometimes there are no clips, and the connector is a push-on fit.
Where are the fuel pipes?
A normal, single fuel pipe begins at the outlet on top or at the side of the tank, where it is usually combined with the electric fuel-tank sender unit which operates the fuel gauge. There is a short pick-up pipe with a filter reaching into the bottom of the tank.
What is a fuel supply line?
A fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another. The United States Environmental Protection Agency defines a fuel line as "all hoses or tubing designed to contain liquid fuel or fuel vapor.

Which fuel pipe line is provided between fuel tank and injectors?
Suction Pipe: Fuel pipe between the fuel tank and the feed pump is called suction pipe. High pressure pipes: The pipes between F.I.P. and the injectors are called high pressure pipes.
What are the two lines on a fuel pump?
There are only two hoses running from the pump. One is the high pressure line, which sends fuel to the injectors. The other is the return line, which dumps fuel that the injectors don't use back into the tank.

What is the best type of fuel line?
The best solution is a material called PTFE. That stands for polytetrafluoroethylene—a plastic material that is best known as Teflon in one specific variation. This material is impervious to the degenerative effects of fuel that also creates a vapor barrier so fuel vapors cannot leak past.
What are the 5 components of fuel system?
To perform at this level, diesel cars must have a fuel system with all of its components (fuel tank, fuel lines, fuel filters, fuel pumps, and fuel injectors) in proper working order. Understanding what these components do aids you in caring for them well.
What is the purpose of a fuel tank vent?
Your tank has to breathe. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. Gasoline expands in volume as it warms up and shrinks in volume as it cools down. The fuel level of your tank changes throughout the day, even if you are not driving it.
What are the different parts of engine fuel system?
There is a fuel pump, fuel tank, fuel lines, fuel filter, fuel injectors, and carburetor. It is really no different than the heart, veins, and kidneys of your body working together to keep you moving. If just one of these components were to malfunction, it could interfere with the entire fuel transferring process.
What is a fuel line?
A fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another. The United States Environmental Protection Agency defines a fuel line as "all hoses or tubing designed to contain liquid fuel or fuel vapor. This includes all hoses or tubing for the filler neck, for connections between dual fuel tanks, ...
What is the rubber hose on a car?
Rubber. Most vehicles have rubber fuel hoses connecting the fuel pipes on the chassis to the fuel pump or carburetor on the engine. Rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.
Where does the fuel pipe go in a car?
A single fuel pipe runs from the tank, under the floor of the car to a mechanical pump on the engine. The pump delivers fuel to the carburettor. Whenever you check fuel pipes, disconnect the battery to prevent stray sparks igniting petrol or petrol vapour. Above all, put out all naked lights and cigarettes.
Where is the fuel pipe?

How to tell if petrol is under car?
If there is petrol under the car after filling the tank, check the flexible hose between the filler neck and the tank neck. A split in the hose will leak petrol as it is being pumped in. Other evidence may be a damp patch or stain under the car.
Why is my fuel pump starving?
Routine checking of all joints for tightness should prevent or cure the problem. Another cause of fuel starvation can be a blockage of the tank ventilation.
How to check if a pipe is blocked?
One clue is that the effect is often spasmodic. If you suspect a blockage, the quickest way to check is to free both ends of the pipe and blow through it. Use your mouth, not a high-pressure air line, which may cause damage. An air line may also loosen dirt, which later falls back and blocks the pipe again.
What is a twin fuel pump?
Twin fuel-pipe system. Twin fuel pipes are checked for leaks in the same way as single ones. Sometimes there is a twin piping system, with supply and return pipes. The fuel pump circulates petrol in an endless loop, from the tank and back again, from which the carburettor draws off as much as it needs.
What is flexible hose?
Flexible hose is usually secured by clips, but may be a push-on fit. Twist and pull the hose gently to remove it. The flexible section of the piping is usually made of reinforced rubber hose , but sometimes clear, flexible plastic tube is used.

Where is the fuel tank located?
The fuel tank is the main storage for the fuel that runs the vehicle. Generally speaking, the gas tank is generally found at, or under, the rear of the vehicle. 2. Fuel Injectors: Sprays a fine mist of fuel into the combustion chamber of each cylinder or throttle body, depending on the design.
How does a fuel pump work?
A fuel pump draws the fuel from the tank through fuel lines and delivers it through a fuel filter to either a carburetor or fuel injector, then delivered to the cylinder chamber for combustion. 1.
Why do fuel injectors burn?
Fuel injectors are more susceptible to damage from dirt because of their close tolerances, but also fuel injected cars use electric fuel pumps. When the filter clogs, the electric fuel pump works so hard to push past the filter, that it burns itself up. Most cars use two filters.
What is the purpose of a fuel pump?
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. There are two types, mechanical fuel pumps (used in carburetors) and electronic fuel pumps (used in electronic fuel injection).
What is the job of fuel injectors?
The fuel injectors are driven by the fuel pump and their job is to spray a fuel and air mixture into the combustion chamber, ready to be ignited to produce power to the driven wheels. The fuel injectors are basically a nozzle, with a valve attached, the nozzle creates a spray of fuel and air droplets (atomization).
What is the function of a fuel system?
The function of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air, vaporized, and burned to produce energy. The fuel, which can be either gasoline or diesel is stored in a fuel tank. A fuel pump draws the fuel ...
