Fuel filters are necessary for the running of any vehicle using fuel. When it ceases to function properly, many other issues may crop up. The filters are found on vehicles of all types. Here are the signs to look for when the filter has gone bad.
Some vehicles can pull heavy loads. When the fuel filter goes bad, the engine can misfire under the strain especially going uphill. The extra fuel may be restricted because the airdog fuel filters are clogged. This typically does not happen in idle due to modern technology limiting the amount of fuel used in idle. However, the added strain of accelerating uphill can cause a misfire due to a blocked filter.
When fuel fails to move through the fuel injectors, the engine loses power. A dirty fuel filter limits the amount of fuel that can move to the injectors. To protect the engine, the ECU restricts the output of the engine. Often, a check engine light appears alerting the driver to a potential issue. The fuel filter is a cheap, easy item to fix that is often overlooked. Check it first then look at other potential causes such as a failed mass airflow sensor or faulty injector.
Cruising uphill, the last thing you want is for the engine to stall. That can happen when the fuel filter becomes clogged with debris. Fuel is unable to move through the filter at the rate needed for hard acceleration. A stalling engine may not happen under normal conditions but crop up when you accelerate hard.
Replacing the fuel filter is not as complicated as it seems. In fact, in many cases, it is easier and less expensive to replace than other items that may be checked first. When your engine has these types of issues, be sure to check the fuel filter when looking for the cause.…
