In general, diesel-powered vehicles require more frequent fuel filter changes than petrol cars. Diesel cars typically need a fuel filter replacement every 10,000 to 20,000 miles, while petrol engines can go between 40,000 and 100,000 miles. It is recommended to replace the fuel filter every two years, regardless of mileage, for both types of engines.

It's important to note that failing to change the fuel filter can lead to clogged fuel lines and poor engine performance. Additionally, your car may struggle to start, and you may experience problems such as stalling, excessive vibration while driving, and rough slow-speed cruising.

When it comes to the cost of changing the fuel filter, the average nationwide price ranges from $90 to $207, including parts and labor. However, the cost may vary depending on your specific Honda model and the service center you choose.

Signs of a bad fuel filter

Although there is no information on how often to change the fuel filter on a 1997 Honda specifically, a fuel filter generally needs to be replaced every 20,000 to 50,000 miles, or every two years.

Engine Won't Start

A clogged fuel filter may prevent your engine from starting altogether. If it does start, it might fire up for a second and then die again.

Engine Stalling

A clogged fuel filter can cause your engine to stall while driving or idling. This can be dangerous, especially if it happens at a red light or stop sign.

Poor Engine Performance

You may notice that the speed and handling of your car are significantly worse, especially when driving at high speeds, going up inclines, or carrying heavy loads. The engine might also surge or sputter, and you may find turning to be more difficult.

Engine Idling and Stalling

When operating at low speeds, a clogged fuel filter will cause your engine to stutter and stall. The bounce of idling might also be more intense than usual.

Power Loss When Under Load

A blocked fuel filter prevents the fuel rail from staying full of fuel, restricting the amount of power your engine can produce.

Check Engine Light Is On

If the injectors don't receive enough pressurised fuel, there may not be enough fuel sprayed into the cylinders to be burned. This can trigger the Check Engine Light.

Excessive Vibration While Driving

If you feel the engine idling roughly or lurching forward, it could be a sign that your fuel filter is clogged.

Rough Slow-Speed Cruising

Your car might be cruising just fine on the highway, but if you experience struggles at slower speeds, it could mean that you need to replace your fuel filter.

Decreased Fuel Economy

A blocked fuel filter can cause higher fuel consumption. The PCM (powertrain control module) believes that the air-fuel mixture is lean, so it commands more fuel to mix with the air being sucked into the engine. As a result, you end up burning more fuel than if the fuel was moving at the right volume.

Fuel filter replacement on diesel cars

The fuel filter in a diesel car is usually much larger than in a petrol car, and the whole fuel system is much more complex. Diesel engine fuel systems are also under a lot more pressure, with modern common rail systems producing over 1000 bar of pressure. Accidentally releasing such high pressure could result in injury, so it is important to know what you are doing.

How Often to Change the Fuel Filter

It is recommended to replace the fuel filter in your vehicle every two years or 30,000 miles. However, this can vary depending on the manufacturer's recommendation, so always check your manual. Some Honda owners recommend changing the fuel filter every 50,000 miles or 5 years.

Signs of a Bad Fuel Filter

• Problems with starting the engine
• Stalling, especially at idle
• Excessive vibration while driving
• Rough slow-speed cruising

How to Change the Fuel Filter

Disclaimer: The following steps are for general information only. Always refer to your vehicle's service manual for specific instructions.

• Relieve the pressure in the fuel system by locating and removing the fuel pump fuse. Then, start the engine and let it run for a minute or two until it dies.
• Disconnect the battery.
• Locate the fuel filter. In most modern vehicles, it is along the fuel line on the bottom of the car, just past the fuel pump.
• Place a bowl or bucket under the fuel filter to catch any fuel that spills out when you disconnect the lines.
• Remove the clips holding the fuel filter in place.
• Disconnect the fuel lines from the filter, tipping them towards the bowl or bucket to catch any spilled fuel.
• Slide the fuel filter out of its bracket.
• Compare the new filter to the old one to ensure they are the same size and will fit correctly.
• Slide the new fuel filter into the bracket and fasten the fuel lines.
• Lower the vehicle if it was jacked up for better access.
• Reinstall the fuel pump fuse.

Fuel filter replacement on petrol engines

The fuel filter is an important component of your vehicle's fuel system, trapping dirt, rust, and other contaminants to prevent them from entering the fuel injectors and damaging the engine. While some newer vehicles no longer have accessible fuel filters, older models do, and it is recommended to replace them every two years or 30,000 miles. Here is a step-by-step guide on how to replace the fuel filter on petrol engines:

Step 1: Locate and Relieve Fuel Pressure

First, locate the fuse or relay for the fuel pump in your vehicle's fuse box. Remove this fuse to prevent the fuel pump from functioning when you start the engine. Then, attempt to start the vehicle. If you've disconnected the correct circuit, the engine will turn over but not start, or it may run for a few seconds before dying.

Step 2: Locate and Remove the Old Fuel Filter

Refer to your vehicle's repair manual to locate the fuel filter. It is typically found along the fuel line, either under the car or in the engine bay. Place a drain pan under the filter to catch any spilled fuel. Next, find and loosen the fuel lines connected to the filter, using pliers if necessary to remove retaining clips. Loosen the screw clamp or bolts holding the filter, then remove and place it aside.

Step 3: Install the New Fuel Filter

Position the new fuel filter in the same way as the old one, ensuring it faces the correct way. There should be an arrow on the filter body indicating the direction of fuel flow, which should point towards the engine. Tighten or clip the new filter into place and reconnect the fuel lines.

Step 4: Reinstall the Fuse or Relay

Finally, reinstall the fuel pump fuse or relay and attempt to start the vehicle. If the vehicle runs normally without any fuel leaks, you have successfully replaced the fuel filter.

Additional Tips:

• It is recommended to change your fuel filter every 5 years/50,000 miles, but this may vary depending on your driving conditions and habits.
• The cost of parts for a fuel filter replacement ranges from $15 to $125, while professional labor costs between $30 and $100.
• Always exercise caution when working with fuel. Wear safety glasses and have a rag handy to catch any spilled fuel.
• Be sure to dispose of the old fuel filter and any used rags properly to avoid a fire hazard.
