Walbro TIA485-2 F90000267 450 LPH Dual-Channel In-Tank Fuel Pump Kit E85 750HP+

Vehicle Fitment

• Universal - No vehicle-specific fitment. Designed for any custom, race, or performance fuel system requiring a high-flow, high-pressure in-tank fuel pump capable of supporting 750+ HP on gasoline or E85/flex fuel. Compatible with virtually all popular performance platforms when paired with the appropriate hanger assembly, fuel module, and installation hardware.

Fitment Notes

• This is a universal in-tank fuel pump kit. Fitment is determined by the hanger assembly, fuel module, and system configuration of the target vehicle. The pump and install kit do not include a hanger or sending unit.
• The F90000267 pump requires modifications to the system wiring, fuel lines, and fuel module for proper installation. Professional installation is strongly recommended.
• This pump features a built-in sealed wiring harness with a female Packard connector. All electrical connections are sealed to ensure full E85/flex fuel compatibility - standard unsealed pump wiring is not suitable for E85 use.
• Compatible with gasoline and E85/flex fuel. All internal pumping components are validated to OEM specifications for approved use in E85/flex fuel applications.
• CAUTION: This pump has an extremely high counterfeit rate. Purchase only from authorized Walbro/TI Automotive dealers. Counterfeit pumps are unreliable, short-lived, and potentially dangerous.
• Not CARB legal for street use in California. Legal for off-road, racing, and competition use only in CA-emissions states.

Features

• Dual-Channel Single-Stage (DCSS) turbine design - single impeller with two parallel rows of turbine blades feeding two independent high-pressure pumping channels simultaneously for maximum flow efficiency
• 20% more efficient than conventional single-channel turbine pumps - delivers superior hot fuel flow with lower current draw and reduced operating noise
• 450 LPH (119 GPH) flow rate at 40 psi and 13.5V in gasoline; 465 LPH in initial flow - supports 750+ HP builds on both gasoline and E85/flex fuel
• Operating pressure range of 35-87 psi covers the full spectrum from OEM fuel pressure specifications to high-pressure forced induction applications
• E85/flex fuel compatible - OEM-validated for approved use with ethanol-based fuels, with sealed electrical connections to prevent corrosion in ethanol environments
• Compact 39/50mm stepped body (39mm upper, 50mm lower) fits a wide range of in-tank hanger assemblies across popular performance platforms
• Award-winning OE technology derived from TI Automotive's work on high-performance production vehicles including the Dodge Challenger Hellcat and Bugatti Veyron
• All-metal construction with validated OEM-spec components for long-term reliability in high-heat, high-pressure fuel environments
• Made in the USA by TI Automotive (parent company and manufacturer of the Walbro brand)

Product Description

The Walbro TIA485-2 is a complete 450 LPH in-tank fuel pump and installation kit built around TI Automotive's award-winning F90000267 Dual-Channel Single-Stage (DCSS) turbine pump. As the successor to older gerotor-style pumps in high-horsepower applications, the DCSS 39/50 represents a fundamental advancement in in-tank pump technology. The innovative dual-channel design uses a single impeller with two parallel rows of turbine blades feeding two independent pumping channels, delivering 450 LPH at 40 psi and 13.5V with 20% greater efficiency than conventional single-channel turbine pumps - meaning more fuel flow per amp of current draw, less heat generation, and reduced operating noise at full load.

The TIA485-2 is designed from the ground up for E85 and flex fuel compatibility. All internal components are validated to OEM specifications for ethanol service, and the pump features a sealed built-in wiring harness with a female Packard connector to prevent electrical corrosion in ethanol fuel environments - a critical distinction from standard gasoline-spec pumps that can fail prematurely when used with high-ethanol content fuels. The pump supports an operating pressure range of 35-87 psi, covering everything from factory fuel pressure requirements to the elevated pressures demanded by heavily modified turbocharged and supercharged builds. At 750+ HP capability on a single pump, the TIA485-2 is the go-to solution for high-output builds on virtually any platform when the appropriate hanger hardware and fuel module modifications are properly executed.

Important: the F90000267 pump requires modifications to the fuel module, system wiring, and fuel lines for installation, and professional installation is strongly recommended. The included 400-1168 universal kit provides the core installation components, but platform-specific hanger hardware and module adapters must be sourced separately for most applications. This pump has an extremely high counterfeit rate - purchase only from authorized Walbro/TI Automotive dealers. Not CARB legal for street use in California. Sold as a complete pump and kit package. Made in the USA by TI Automotive.
