Fuel Systems – Auto Repair Metairie

For a smooth driving experience it is a prerequisite that all the parts and components of your vehicle function at its optimum level and that includes the fuel system. A leak, crack, poor fuel economy, stalling or misfiring is enough to get your fuel system in trouble.

Since a fuel system in itself is made up of many elements, it is necessary to diagnose the problem and area and eliminate other possible options and prevents you from making unnecessary changes. An inspection and diagnosis will pinpoint whether the trouble lies with ignition or compression, if the engine is flooded with fuel or is it simply an empty tank.

Our technicians at CARS are trained & certified to diagnosis, repair and service your automotive Fuel Systems:

Gas Fuel Injections

Gas fuel injections are performed by a fuel injector – that component of the fuel system which decides the amount of fuel that will be pumped in whenever you step on your car’s gas pedal. This electronically controlled valve is capable of controlling its opening and closing at the rate of many times per second, and is supplied with pressurized fuel by the fuel pump in your car.

When you step on the gas pedal, the injector gets energized, and an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle. The nozzle is designed in such a way that it makes a fine mist out of the pumped fuel so that it can burn easily. The amount of fuel supplied to the engine by gas fuel injections is determined by the amount of time the fuel injector stays open.

Fuel Lines

Fuel lines perform the function of transporting the fuel to the different parts of your car’s engine. For a car to function properly and at its optimum level, it needs fuel, and the fuel needs to reach all the relevant components for a smooth drive.

The fuel line is shaped like a hose and is made of rubber for flexibility purpose and to prevent it from breaking or cracking. If you experience very cold weather, you need to prevent the fuel lines from freezing up. A fuel de-icer can do the job and keeps the gas flowing through the lines.

Fuel Hose

Fuel hose is similar to fuel lines, and is that part of your vehicle’s fuel system which performs the role of carrying fuel or gas within the car. In fact, fuel hoses are used not only in a vehicle but also in plants and machineries for the same purpose of supplying fuel.

It is made of synthetic rubber tubes that are flexible. This ensures that it can be conveniently flexed to connect without breaking or cracking, can perform under high pressure and soaring engine temperatures. And also the material used in a fuel hoses manufacture prevents it from getting corroded due to rust or any leakage.

Fuel tank

A fuel tank is a container for storing flammable liquids like petrol or diesel in cars. It is a part of the engine system where the fuel is stored and pumped. Fuel tanks can vary in size. When the fuel is pumped, it releases the pressurized gas in the engine.

You need to keep checking the fuel tank at regular intervals as in case of a leak or crack, it may lead to firing up of your vehicle. It is recommended to use premium quality to avoid damage.

Fuel Gauges

Fuel gauges are used to indicate the fuel levels in a tank. They consist of two main parts – the sensing unit and the indicator. The sensing unit uses a float which is connected to a potentiometer. When the fuel level drops or the tank empties, the float drops and resistance increases. When the resistance increases, the low fuel indicator starts flashing on your car.

The indicator measures and indicates the amount of electrical current flowing through the sending unit. When the current flow is high and the fuel tank is full, the indicator shows “F” thereby indicating fuel tank full and “E” when the tank is empty.

A faulty fuel gauge can be very inconvenient. You don’t want to run out of gas when you’re on a long drive and there’s no fuel pump in sight for miles. Your mechanic can replace a defective gauge.

Fuel pumps

Fuel pumps are often crucial components of a car or internal combustion engine. Some older engines, such as those used in motorcycles, do not require fuel pumps. In a vehicle where the fuel tank is positioned on the opposite of the engine, fuel pumps play an essential role in sending gas to the side where the engine is located.

Mechanical fuel pumps are those used in carbureted cars while cars with an electronic fuel injection system used electrical fuel pumps. Mechanical fuel pump help the carburetor deliver gas to the engine using vacuum. The electronic fuel injection system is controlled by a computer that controls the fuel delivery system. It injects fuel into the engine’s combustion chambers via the fuel pump that is positioned near the fuel tank.

Electronic fuel injection systems rarely fail but when they do, your car will not restart, even if the gas tank is full. Check the fuel delivery end and see if there is fuel going into the engine. If it isn’t the fuel pump is likely to have broken down. Replacing an electronic fuel pump that has failed is best left to a professional car mechanic.

Fuel Filters

Fuel filters are designed to filter out junk and debris in gas and prevent large particles from clogging up the fuel system, which can seriously damage the car engine. They are located along the fuel lines and are crucial to the engine’s performance.

Different fuel delivery systems have different fuel filters. In carbureted engines, metal or plastic is used for the fuel filters, while cars with electronic fuel injection systems have metal fuel filters. These components only work well if the flow of gas travels in the right direction. Usually this is easy as the “in” and “out” sides are clearly marked.

It is recommended that you change your car’s fuel filter at least every two years, and more often if you live in a highly-polluted area, since a clean filter can improve your car’s performance.
