Fuel Module, GM SUV, High Perf. 450LPH

Racetronix TU464HP-2
GM SUV High-Performance Fuel Module | 400 LPH Effective Flow

Quick Overview

  • Genuine TI Walbro Drop-In Module assembly.
  • High-Performance Pump: Equipped with TI Walbro DCSS Turbine technology. While commonly marketed by competitors as a "Walbro 450" module, Racetronix provides an engineered "Effective Flow" rating. This accounts for the fact that a standard "450" pump actually flows ~430 LPH at base pressure, and volume is further reduced by the internal jet-pump requirements and the higher operating pressures of this specific GM system.
  • Internal Regulator: Retains the factory-style internal regulation for seamless integration with the OEM fuel system.
  • E85 Compatible: Certified for use with Ethanol and Gasoline blends.
  • MANDATORY REQUIREMENT: Must be used with Racetronix FPWH-022 Upgrade Harness to handle increased current draw.

Technical Specifications

Effective Flow Rate ~400 LPH @ 43.5 PSI (13.5V)*
Regulation Internal (Standard Factory Configuration)
Pump Technology DCSS Turbine (High-Performance "450-Style" Pump)
Compatibility Gasoline, E85, E10, Race Fuels

*Flow Note: Industry competitors often quote the bare pump's theoretical rating of 450 LPH. However, in a regulated module environment with internal jet-pump requirements and standard operating pressures, effective volume is approximately 400 LPH. Racetronix provides these conservative ratings to ensure system reliability and engine safety.

The TU464HP-2 represents the ultimate drop-in solution for GM SUV owners seeking high-volume fuel delivery without the complexity of external pump setups. By pairing a factory-fit module with a high-performance Walbro turbine pump, this unit provides significantly increased effective fuel volume while maintaining full support for E85 environments.

Installation Note: This module is a high-amperage component. Standard factory wiring and the underhood electrical center (fuse/relay block) are not rated for the sustained load of this high-output pump. Failure to use a dedicated heavy-gauge relay harness (FPWH-022) will result in terminal burnout, connector failure, or significantly reduced pump performance due to voltage drop.

Attention: Mandatory VIN Fitment Verification

The customer is solely responsible for determining correct fitment based on the vehicle’s VIN (Vehicle Identification Number).

GM truck and SUV platforms often utilize up to five or more different fuel module configurations for the same model year. Factors such as tank capacity, emissions standards, and cab configuration change the module requirements. Searching by vehicle type and trim level is insufficient; the VIN is the ultimate "Go / No-Go" check for fitment.

How to Verify Fitment:
  1. Find your 17-digit VIN (found on your dashboard or door jamb).
  2. Visit GM Parts Giant or GM Parts Direct and enter your **VIN** to find your exact **OEM Part Number**.
  3. Cross-reference that OEM number on the Delphi Parts Catalog to find the Delphi **Interchange Number**.
  4. Verify that the Delphi number (e.g., **FG0340**) or the GM OEM number matches our **Interchange List** above.

If you are unsure of the results, please reach out to Racetronix support with your VIN before placing your order.

Return Policy Notice: We will not accept returns on open-box fuel pump modules due to shipping costs and liability concerns.
