How much does it cost to replace a fuel filter on a Subaru Impreza?
On most Subaru Imprezas, replacement costs can range from about $70 to $1,000, depending on whether a separate filter is serviceable or the fuel pump assembly must be replaced. The exact price depends on model year, fuel filter location, and local labor rates.
Understanding how the fuel filter is configured in the Impreza
Subarus built in recent years often place the fuel filter inside the fuel pump module in the tank, meaning replacement may involve the entire pump assembly rather than a standalone filter. Some older or certain trim levels may have an inline filter that is accessible from under the hood. If you’re unsure which setup your car uses, consult the owner's manual or ask a qualified mechanic to confirm before quoting a price.
Cost scenarios follow to illustrate typical pricing you may encounter at a shop or dealership. Each scenario reflects common practice in the United States as of 2024–2025 and can vary by region and labor rate.
- Inline fuel filter replacement (serviceable separately on older Impreza models):
- Part cost: roughly $10–$60
- Labor time: about 0.5–1.5 hours
- Estimated total: commonly $70–$250, depending on shop rates
Note: Inline filters are less common on newer Impreza models; when present, they tend to be the cheaper option for replacement.
Cost scenarios continue for the fuel pump module replacement, which is common when the filter is integrated into the pump in the tank.
- Fuel pump module replacement (filter inside the pump):
- Parts cost: roughly $150–$700 (OEM versus aftermarket; OEM typically higher)
- Labor time: about 2–4 hours
- Estimated total: commonly $400–$1,200 or more, depending on pump choice and labor rate
Costs are higher when the repair is performed at a dealership or when additional services (like tank priming or fuel system diagnostic work) are needed.
What affects the final price
- Model year and trim level of the Impreza
- Whether the filter is serviceable as a separate part or part of the fuel pump module
- Labor rates in your area and whether the work is done at a dealer, independent shop, or quick-lube facility
- Availability of aftermarket versus OEM parts
In practice, many Impreza owners end up paying on the higher end if the fuel pump module must be replaced, due to the cost of the pump and the longer labor time.
Summary
The cost to replace a fuel filter on a Subaru Impreza varies widely. If your car has a serviceable inline filter, expect roughly $70–$250. If the filter is inside the fuel pump module, replacement typically runs about $400–$1,200 or more, depending on parts choice and labor rates. Always confirm with a local shop whether your model uses a separate inline filter or a pump-module assembly, and obtain multiple quotes to ensure you’re getting a fair price.
Takeaway
When facing a fuel filter replacement, confirm the filter type and location for your specific Impreza model year, as this drives the price significantly. A quick diagnostic with your mechanic can clarify whether you’re dealing with a standalone inline filter or a pump-module replacement, which helps you budget accurately and avoid surprises.

- Average range: $90 to $207 (parts and labor)
- Factors affecting cost:
- Model and year: The cost will vary significantly between different models and their respective model years.

- Labor costs: These can differ based on your geographic location and the type of service center you use.
- Part cost:
- In-line filter: These are typically less expensive. For example, a specific part for some older models has an MSRP of around $42.58.
- Fuel pump assembly: If the filter is in-tank, you may have to replace the entire fuel pump assembly, which is more costly.

What are the symptoms of a bad fuel filter?
Symptoms of a bad fuel filter include difficulty starting the engine, rough idling, stalling, poor acceleration, reduced fuel economy, and the check engine light coming on. A clogged filter restricts fuel flow, causing the engine to run poorly and potentially leading to further damage if not addressed.
Performance issues
- Difficulty starting: The engine may crank but not start, or it may take longer to turn over because not enough fuel is reaching it.
- Engine stalling: The vehicle may stall, especially when slowing down, idling, or under heavy load, due to insufficient fuel.
- Rough idling or misfires: The engine may run unevenly, causing shaking at idle, or experience misfires, which can lead to a loss of power.
- Hesitation and poor acceleration: The car may hesitate, stumble, or feel sluggish when you press the gas pedal, especially when accelerating or climbing a hill.
- Loss of power: The vehicle may feel underpowered, particularly at high speeds or when carrying a heavy load.
- Poor fuel economy: The engine works harder to pull fuel through a clogged filter, which can lead to decreased mileage.
Other indicators
- Check Engine Light: The light may come on, often with codes related to a "lean condition," which means the engine is getting too much air and not enough fuel.
- Fuel pump noise: The fuel pump may make unusual or loud noises as it works harder to push fuel through a clogged filter.
- Fuel odor: A strong fuel smell can indicate a leak or that the engine is burning fuel inefficiently.
