If you end up with a clogged fuel system you won’t be able to start your car. Fuel system maintenance is just as important as oil changes, and McCurley’s Shell can service your vehicle’s fuel system when it needs it to ensure you don’t end up with a clogged fuel system. There are four common places where these clogs can occur. Here’s what they are and what you can do to avoid them.
The gas that is sitting in your gas tank has sediment in it. Even if you buy 91-octane at our service station, it will still have a small amount of sediment. This is natural with all gasoline, which is why your automobile has a fuel filter. The filter not only traps the sediment in the gas, but it also traps dirt, organisms, and other contaminants that are harmful to your engine. Change your fuel filter every 24,000 miles or two years to prevent it from getting clogged.
The fuel injectors are clogged by carbon buildup. As your combustion chamber burns oxygen and gasoline, carbon builds upon the various parts, including the fuel injectors. Carbon is a natural combustion engine byproduct, i.e. you can’t avoid it any more than you can avoid gas sediment. Clogged fuel injectors will make your engine struggle for power and sputter. Have the fuel injectors cleaned every 60,000 miles to remove the built-up carbon deposits.
Older fuel lines can also get clogged. If they do, you’ll notice some pretty disturbing signs. For example, if you have a blocked fuel line, you might end up with smoke inside your vehicle’s interior.
This is dangerous, as the smoke contains carbon monoxide, and indicates you’ve got gas flowing back into the tank and leaking into your engine. Clogged fuel lines will also prevent your car from starting. Cleaning or replacing the clogged fuel lines solves the problem.
Finally, your fuel pump can get clogged by gas sediment, dirt, and rust. The fuel pump is susceptible to clogs because it draws the gas out of the tank. If you like to push your vehicle between fill-ups until your low gas light comes on, you’re drawing even more dirt, rust, and sediment through the fuel pump because it’s pulling the small amount of gas left from the bottom of the tank. You can prevent fuel pump clogs by purchasing quality gasoline and keeping your tank full.
If your automobile is having a hard time starting, accelerating, or sputtering and stalling, you might have a clog in your fuel system. Stop by McCurley’s Shell in Atlanta, GA, so we can check it out.
