When it comes to maintaining or upgrading your Scion FR-S, one component that often gets overlooked until there’s a problem is the fuel pump. This critical part of your vehicle’s fuel system ensures that gasoline flows consistently from the tank to the engine. If you’re dealing with symptoms like engine sputtering, loss of power during acceleration, or difficulty starting the car, a failing fuel pump might be the culprit. But what fuel pump fits a Scion FR-S, and how do you choose the right one? Let’s break it down.
First, it’s important to understand that the Scion FR-S shares its platform with the Subaru BRZ and Toyota 86. This means many parts, including the fuel pump, are interchangeable across these models. The OEM (Original Equipment Manufacturer) fuel pump for the FR-S is designed by Denso, a trusted name in automotive components. The specific part number for the stock fuel pump is **Denso 950-0158**, which is compatible with 2013–2016 FR-S models. However, if you’re driving a later model or have modified your car for higher performance, you might need to explore aftermarket options.
For those sticking with factory specifications, replacing the fuel pump with an OEM-equivalent part is the simplest solution. These pumps are built to meet the exact requirements of your FR-S, ensuring reliable performance and longevity. But if you’ve upgraded your engine, added a turbocharger, or tuned your car for racing, a stock fuel pump might not deliver enough pressure or volume to support the increased demands. This is where high-performance fuel pumps come into play. Brands like Walbro, AEM, and DeatschWerks offer upgraded fuel pumps that can handle higher horsepower and improved fuel efficiency. For example, the **Walbro 450 LPH Fuel Pump** is a popular choice among FR-S owners who’ve modified their vehicles for track use or forced induction setups.
Installation is another factor to consider. While swapping a fuel pump isn’t the most complicated job, it does require careful attention to detail. The fuel tank needs to be safely depressurized and partially lowered to access the pump assembly. If you’re not confident in your mechanical skills, it’s worth consulting a professional. However, many enthusiasts tackle this project themselves using online tutorials and service manuals. Just remember to disconnect the battery and work in a well-ventilated area to avoid safety hazards.
Maintenance is key to prolonging the life of your fuel pump. Always keep your gas tank at least a quarter full to prevent the pump from overheating. Contaminated fuel can also damage the pump, so avoid filling up at stations with outdated or poorly maintained tanks. If you’re installing an aftermarket pump, regular inspections are recommended—especially if you’re pushing your FR-S to its limits on the track.

In summary, the Scion FR-S requires a fuel pump that matches its engineering specs or your modified goals. OEM options like the Denso 950-0158 are ideal for stock vehicles, while aftermarket upgrades from Walbro or AEM cater to high-performance builds. Prioritize quality, compatibility, and safety, and your FR-S will thank you with reliable power and responsiveness.
