Part number: wal F90000274
This is the high pressure 450lph fuel pump by Walbro (F90000274). This fuel pump does not come with an install kit and is sold separately. We recommend this install kit if you need one :)
Operating pressure: 35-112psi
Compatible fuel(s): E10 (87, 91 and 93 octane pump fuel), E85, race gas (110-116 octane fuel)
Location: Submerged in-tank fuel pump
Is this fuel pump right for me? Our recommendation is anything stock-450hp to the tire (on E85), use this pump or the low pressure Walbro 450lph single pump. That way you have ample fuel to make your power goals. 500+, I’d do the Hellcat pump (F90000285). And then 650+ I’d do a twin or triple pump setup with any of these flavors.
Why high pressure over low pressure? The high pressure pump is safer for higher fuel pressure. Most cars run a 43.5psi base pressure, with a rising rate regulator. Often times you'll super high fuel pressure depending on your setup at WOT (wide open throttle).
Technical jargon:
These fuel pumps are considered Dual Channel Single Stage (DCSS) pumps that are turbine driven. They create fuel pressure by centrifugal force from a turbine wheel inside the housing thereby forcing fuel into the fuel line – that basically means that they can flow a good amount of fuel to make big power. Turbine style fuel pumps are best for high horsepower applications requiring higher fuel pressure. That’s why these have such a unique shape compared to the old school GSS342 (Walbro 255lph). Back in the day, throw a 255 in the car and race gas and you’re set to make some decent power! Nowadays with ethanol and the potential capabilities of ethanol based fuels, much more fuel flow is needed to support how fast ethanol burns.

Good and reliable
Will require some trimming on both evo 7/8/9 pump craddle or sti newer than GDB (2008+). Syphon will probably also have to be drilled out and hardwire must be used to avoid burning up the stock wires. Wicked high volume pump.
