Walbro F90000274 460lph E85 In-Tank Fuel Pump (Walbro 460)
Fits: Universal in-tank pump. A direct fit in the Radium Engineering 86 / BRZ / GR86 dual pump hanger (Radium-verified). It won't drop straight into the factory 86 / BRZ pump module.
The Walbro F90000274, commonly known as the Walbro 460, is a high-pressure, E85-compatible in-tank pump made in the USA by TI Automotive (Walbro's parent company). It's a popular choice for twin-pump setups in high-power 86 / BRZ / GR86 builds on E85.
Key features:
- E85, ethanol and petrol compatible
- Single impeller with two parallel rows of turbine blades for high flow at high pressure
- Higher maximum pressure than the F90000267 (different internal relief valve)

FAQ
Is this the "Walbro 460"?
Yes. The F90000274 is the pump commonly sold as the Walbro 460 (E85, high-pressure version).
Will it fit my factory 86 / BRZ pump module?
Not as a drop-in. It's designed for aftermarket hangers like the Radium dual pump hanger.
One or two pumps?
Two pumps in a dual pump hanger are recommended for high-power E85 builds. Ask us for advice on your power goal.
