Signs of a bad fuel filter

A fuel filter keeps fuel running smoothly to your engine. It is important to change your fuel filter on time to protect your vehicle's engine and maintain power and gas mileage. Here are some signs that indicate it is time to replace your fuel filter:

Engine Won't Start

There could be many reasons why your vehicle won't start, but a clogged fuel filter is a major one. If you ignore this, you may go from having trouble starting your engine to not being able to start it at all.

Engine Stalling

A clogged fuel filter will cause your engine to stutter and stall, especially at low speeds. This is because a clogged filter results in less fuel being given to the engine.

Engine Misfiring or Rough Idling

A clogged fuel filter can cause low fuel pressure, which may lead to an engine misfire as well as rough idling. This can cause additional problems for your engine.

Poor Engine Performance

You may experience a sudden drop in fuel efficiency, and you may find that your engine surges or sputters, especially at high speeds, inclines, or when carrying heavy loads. A clogged filter interferes with the amount of fuel put into the engine, causing a range of problems.

Trouble Accelerating

If your fuel filter is clogged, not enough fuel may be able to flow, causing problems when accelerating your vehicle.

Check Engine Light

Your car's engine computer looks for problems that could lead to an increase in emissions. Usually, the device will recognize these issues, turn on the check engine light, and store a corresponding diagnostic trouble code (DTC) in its memory.

A Damaged Fuel Pump

A bad fuel filter can cause the rest of your system to compensate, putting it under duress and potentially damaging your fuel pump.

Frequency of replacement

The frequency with which you should replace the fuel filter in your Acura TLX depends on several factors. Firstly, it is recommended to refer to the owner's manual for specific maintenance intervals. Additionally, car companies generally advise changing the fuel filter every 5 years/50,000 miles. However, this may vary based on factors such as your driving habits, where you live, and the condition of the fuel filter.

Some signs that indicate it's time to replace the fuel filter include:

• Problems with starting the vehicle, such as taking multiple attempts.
• Stalling, especially while idling at a stop sign or red light.
• Excessive vibration while driving, with the engine idling roughly or lurching forward.
• Rough slow-speed cruising, where the car struggles at slower speeds but performs fine at highway cruising speeds.
• Difficulty starting the engine or an inability to start the vehicle.

Fuel filter location

The fuel filter in the Acura TLX is located inside the fuel tank, attached to the fuel pump.

To access the fuel filter, you will need to release the fuel system pressure and remove the fuel pump. This process involves several steps, including:

• Removing the spare tire compartment lid and the access panel from the floor.
• Disconnecting the fuel pump 5-pin connector and the negative battery cable.
• Releasing the fuel pressure by loosening the fuel pulsation damper.
• Disconnecting the quick-connect fittings from the fuel pump and removing the fuel pump assembly bolts.

It is important to note that fuel pressure should always be released before disconnecting any fuel injection-related components. Additionally, fuel should not be allowed to contact engine or electrical components.

Some Acura TLX models may also have a pre-screen fuel filter located under the hood, usually next to the firewall.

According to some sources, the fuel filters in Acura products since 1995 are designed to last a lifetime and never need replacement. However, it is recommended to consult a professional mechanic or refer to the vehicle's service manual for specific information regarding fuel filter replacement intervals and procedures for your particular Acura TLX model.

Performance issues

Performance-related issues are a clear sign that your Acura TLX's fuel filter needs to be replaced. Your car needs fuel to operate, and when the fuel filter is clogged, damaged, or compromised in any way, your engine may not receive the right amount of fuel. This can lead to a variety of issues that you will notice when driving.

The car might misfire due to incomplete combustion, and you may notice a lack of power as your car doesn't respond as expected when you press the accelerator. This lack of power may be more noticeable at slow speeds, as the engine isn't working as hard. At faster speeds, the higher pressure can help force the fuel past a clogged filter, which may not be possible at lower speeds.

You may also experience hesitation when starting or accelerating, which can be a strange sensation. If your car is stalling, it could be because a clogged fuel filter is preventing enough gasoline from reaching the combustion chamber, causing the car to stall when you come to a stop.

If you're experiencing performance issues, it's important to address them promptly. A fuel filter that needs to be replaced can cause a serious loss of performance, and eventually, your car may not start at all.
