5 Signs Your Car Needs a Fuel System Service

It should come as no surprise that your fuel system is very important to the overall health and performance of your engine. From the gas tank to the fuel lines and filter, each component works together to supply clean fuel to the engine's combustion chamber. If the fuel is contaminated, dirty or not flowing properly, your vehicle won't run as well and it can eventually cause significant damage to the engine or exhaust system.

So, how do you know when you might have a fuel system problem? Here are 5 common signs you can look out for:

1. Loss of Fuel Efficiency

If you notice that your miles per gallon (MPG) have gone down, it could actually be any number of automotive problems including the engine, exhaust system, wheel alignment, tire air pressure and other systems. The fuel system might also be the cause. There could be a clog in one of the fuel lines or the filter may need to be replaced. A significant loss of fuel efficiency is definitely a sign you have a problem, so get your vehicle checked out by an automotive expert to diagnose the source(s).

2. Check Engine Light is On

Again, your check engine light can come on for many different reasons. It may be anything from a failing oxygen sensor to an exhaust leak. You should never wait to long to get your check engine light tested and inspected by a knowledgeable mechanic to determine what is causing the light to illuminate. A fuel system failure could be one potential issue.

3. Sluggish Acceleration

As a driver, you can usually feel when your car doesn't seem to be running right. A common problem is when it feels very sluggish during acceleration. This could be the sign of a fuel system problem. It could also be the transmission, exhaust or something else.

4. Trouble Starting the Car

A lack of clean fuel in the engine may make it difficult to start the car up in the morning. If you are experiencing this issue, it might be a fuel system problem such as a clogged fuel line. Again, it may be something else like a dying battery, failing starter, bad spark plug or weak electrical connection.

5. Rough Idling

Lastly, you may find that your car rumbles and shakes when you are idling at a stop. The engine may backfire or make strange noises, as well. This is often a telltale sign of a fuel system issue or something wrong with the engine itself.

You may need repairs or you may simply be due for a fuel system service.
