Your vehicle’s fuel system is crucial for powering your engine, and by extension every other system in your vehicle as well. With the wild fluctuations in gas prices, everyone is looking for ways to get more out of each drop of fuel. That’s why having a properly service fuel system is so important. There are a number of points where a leak or fault can occur, and that can lead to wasted gas and expensive fill ups. Until we finally figure out practical electric cars, or until we make a new source of fuel more economical, fuel system repairs will continue to be an important part of vehicle ownership, and the experts at Gary’s are here to help!
Filling Up Your Tank
Your fuel system begins at the gas cap. You normally wouldn’t pay much attention to this part of the system, but this tiny cap can have the power to set off your vehicle’s check engine light. A securely fitting cap is important to prevent evaporating gas on on hot days as well (although with most modern tanks this isn’t much of an issue).
After you’ve finished pumping gas into your car it sits in the tank. Traditionally, fuel tanks were made of steel or aluminium, due to the limited availability of other materials. In more recent years, the vehicle fuel tank has been replaced with high density polyethylene (HDPE). This fuel tank allows for a wider variety of shapes and sizes, and has better emissions that traditional steel or aluminium. The ability to completely customize the size and shape of HDPE tanks as well as the savings in weight make HDPE the new standard. The downside to these new plastic tanks is that while an old steel tank could be patched if a hole was present, HDPE tanks are often replaced entirely.
In older vehicles with carburetors, fuel was pulled from the gas tank via the fuel line by the fuel pump, located near the engine. Today, fuel injection has replaced carburetors, and the fuel pump has also moved. While it may sound counter-intuitive, the electronically controlled fuel pump is located in the fuel tank and is submersed in gasoline. Liquid gasoline doesn’t combust, so this is actually the safest place for the pump, as the constant coating of gasoline keeps the pump cool. If you’re a driver who frequently drives on empty, this is where you may notice a fault in your vehicles fuel system. Given that gasoline cools the fuel pump, driving on empty can cause the fuel pump to prematurely wear out.
After the fuel is pumped to the engine, it is used in the fuel injection system (or older carburetor) systems. Your car doesn’t burn just gasoline, it burns a mixture of air and gasoline. The perfect ratio of this mixture is 14:1, where 14 parts air is mixed in for every 1 part of fuel. The fuel injection system is responsible for injecting that 1 part fuel into a mixture of 14 parts air.
When Is It Time For Service?
When it comes time for fuel system repairs, preventative maintenance is your best friend. Since no system in your car is working to repair itself, knowing exactly when something is wrong can save you massive amounts on repairs.
Starting with the fuel tank, a leak is an easy problem to diagnose. You’ll notice the trademark smell of gasoline coming from your vehicle, and you may notice pools of gas in your garage or on your driveway. Gas tank repairs are fairly easy to complete, either repairing what can be repaired or simply replacing the tank entirely.
A faulty fuel pump can lead to a number of symptoms. Since the fuel pump is responsible for delivering fuel from the tank to engine, any signs of that being disrupted can be attributed to a faulty fuel pump. Things like sudden gains or losses in acceleration, or the engine simply failing to start can be signs of a bad fuel pump.
Finally, the most common issue with your fuel injection will be the nozzles becoming dirty or clogged. When this happens, you’ll notice a rough or loud idle, or you may smell gasoline coming from your engine. You may also notice decreased gas mileage.
