Most car owners don’t think about how fuel moves from the gas tank to the engine. Yet, a problem in any part of the journey can cause all kinds of problems. When you need fuel system repair, bring your car to Havoline® Xpress Lube of Kernersville.
Signs You May Need A Fuel System Repair
Most automakers design vehicles with combustion engines that rely on gasoline to power them. For your engine to run efficiently, it needs the correct mix of oxygen and gas to create power.
A malfunction in any part of your fuel system will prevent the correct amount of fuel from reaching your engine. When this happens, you may experience one or more of the following problems:
Does driving a car with reduced gas mileage really matter? For some drivers, continuing to drive with a faulty fuel system may not seem like much of a big deal. However, a failing part like a fuel pump can die at any time leaving you stranded.
Furthermore, anytime one part isn’t working efficiently, it affects your entire engine. Thus, you may cause more extensive and expensive damage. For example, repeated misfiring allows unburnt fuel to foul up the catalytic converter. Misfires can also strain other engine components leading to early failure.
Self-Diagnosing A Fuel System Problem Can Be Complicated
Some car repairs can be relatively inexpensive and simple to fix on your own. For example, changing your engine air filter and wiper blades is generally easy. You can also check your oil and coolant levels adding fluids as needed.
However, correctly diagnosing many engine problems is usually complicated. Many times, different malfunctioning parts will produce similar symptoms.
For example, a clogged fuel filter or bad spark plug can cause misfiring. Additionally, dirty fuel injectors or bad spark plugs could cause rough idling. Plus, there are plenty of reasons why your car won’t start. You may have a failed pump, dead battery, or broken alternator.
That’s why it’s important to bring your car to a qualified mechanic like Xpress Lube. Our ASE-certified mechanics will correctly diagnose your problem and fix your issue quickly to get you back on the road.
Common Causes Of Malfunctioning Fuel System
Usually, the most common reasons you have a problem with your fuel system is due to one of the following causes:
- Failed fuel pump
- Clogged fuel filter
- Dirty/clogged fuel injectors
- Blocked or leaking fuel line
One problem with fuel systems is a broken pump. Generally, manufacturers build fuel pumps to withstand the life of your car. However, wear and tear can take its toll.
Furthermore, most manufacturers locate the fuel pump inside the gas tank so that the fuel cools and lubricates the pump. Consistently driving with low levels of gas leads to increased temperatures and premature wear on your pump.
Another common problem is a clogged fuel filter. Over time trapped contaminants in the filter can block fuel from flowing past to the engine. Typically, you need to change this filter every 30,000 to 60,000 miles. However, in some modern cars, automakers use lifetime filters that don’t need changing unless you replace the fuel pump. Always check your owner’s manual for specifics on your vehicle.
Fuel injectors are another place where you can experience problems. Typically, no matter how efficient your engine is, there will still be some unburnt fuel. Under intense engine heat, some of this unspent fuel will bake onto the injections. These dirty fuel injectors may cause misfiring, rough idling, and reduced efficiency. Thus, you should periodically clean off these carbon deposits.
Moreover, dirt or debris can travel from the tank and lodge in a fuel line. Once trapped there, it can prevent gas from reaching the combustion chamber. Finally, about 98% of U.S. gas contains ethanol, a renewable fuel made from plants. Ethanol is highly corrosive and can degrade rubber and plastic engine components causing leaks.
Car Repair FAQs
Modern vehicles are complex integrated systems requiring all components to work properly. Keeping your fuel system well-maintained protects other engine parts from stress and early failure. Below, we answer a few commonly asked questions about fuel system repair.
How Much Is A Fuel System Repair Cost?
Ultimately, the answer to this question depends on your diagnosis. For example, a new fuel pump may cost about $1000. While a fuel injector cleaning averages about $150. When we service your car, we’ll diagnose your problem and quote you a price before we begin any work.
What Routine Maintenance Does My Fuel System Require?
As with many car parts, a little maintenance can keep your car running efficiently longer. Thus, performing these simple tasks can help keep your car’s fuel system in good condition:
- Routinely clean your fuel injectors
- Change your fuel filter as directed by the manufacturer
- Don’t let your gas level fall below ¼ of a tank
