The best Full Blown product here for an FR-S or BRZ owner is its only entry: the Full Blown FRS/BRZ Walbro 485 Fuel Pump Kit. Dealer listings describe it as a kit for owners needing more fuel without a dual pump setup, fitting the Walbro 485 inside the tank while retaining the OEM venturi system, filter and lines. Check your year and model first: the title names the FRS and BRZ, with no year range.
An in-tank fuel pump delivers fuel from the tank at the flow and pressure the tune demands. A stock pump can become the limiting part when fuel needs grow, which is why kits for this platform are sold as complete fitting solutions, not bare pumps. The value is in what keeps working around the bigger pump: here, the factory venturi system, filter and lines.
Shop the wider fueling ranges alongside it: Fuel Systems, Subaru BRZ 2013-2021 Fuel System Parts, and Walbro High-Flow Fuel Pumps. For the build context, read a guide to Subaru engine modifications.
Brands to know
Full Blown is carried here through this single fuel kit, and its dealers state its intent plainly: more fuel for the FRS and BRZ without a dual pump setup, with the larger pump fitted in the tank and the OEM venturi, filter and lines retained. Judge the brand through that kit: a platform-specific solution, not a universal pump. One dealer note matters: the OEM basket is not included.
Walbro is the pump maker named in the kit's title, and its range here shows the sizes around it: 255 lph kits for earlier WRX and STI models, and 450 lph in-tank E85 pumps. Dealers identify the Walbro 485 named here with the F90000267 pump, the 450 lph E85 version also sold on that shelf.
DeatschWerks is the other fuel specialist for this platform here, carried for the DW300c pump with install kit listing the 2015-2021 WRX and 2013-2016 BRZ and FR-S, and for install and hardwire kits covering the BRZ, FR-S and 86. Cross-shop it for a pump and kit matched as one part number.
Radium Engineering covers the supporting hardware around a pump upgrade, carried here for a hanger built for Walbro 450 lph pumps, a DIY pump wiring kit in the BRZ fuel range, and fuel rail plumbing kits. Cross-shop it when a swap grows into hangers, wiring and rails.
FAQ
Which cars does this Full Blown kit fit?
The title names the FRS and BRZ, with no year range. Dealer listings for the same kit name the FR-S and BRZ from 2013, but check your year and model against this listing first.
Is the OEM fuel pump basket included?
No. A dealer note states the OEM basket is not included, so plan on working with the basket in your tank and confirm the kit contents on the listing.
Does a bigger fuel pump need a tune check?
A pump changes fuel system capacity, and fueling changes should be verified, not assumed. Have air-fuel ratios checked after installation, especially on a tuned car.
Can this pump run E85?
Dealers identify the Walbro 485 here as the E85-compatible F90000267. The rest of your system and tune must also suit ethanol, so confirm injectors, lines and calibration before switching fuels.
