Quick Overview

• Genuine TI Walbro Drop-In Module assembly.
• High-Performance Pump: Equipped with a specialized TI Walbro turbine pump featuring an integral Venturi jet-pump. This design ensures the module remains full of fuel even under low-tank or high-slosh conditions, preventing pump starvation.
• Internal Regulator: Retains the factory-style internal regulation for seamless integration with the OEM fuel system.
• MANDATORY REQUIREMENT: Must be used with a Racetronix Upgrade Harness to handle increased current draw and prevent factory fuse block failure. This harness along with other options are listed under the add-on section at the bottom of this product page.

Technical Specifications

*Flow Note: This modern turbine design maintains a true 255 LPH at the standard GM 58 PSI operating pressure, outperforming legacy gearotor designs. Racetronix provides these engineered ratings to ensure system reliability and engine safety.

Fuel Compatibility & Liability Note: This module is not certified by TI Automotive for use with high ethanol concentrations (E85) or various types of specialized race fuels. Depending on additives, certain race fuels can be highly aggressive and will shorten pump life. If utilized for racing applications with aggressive fuels, the system must be purged immediately after use; do not leave the module submerged in such fuels for extended periods. Racetronix assumes no liability for pump failure or system damage resulting from applications that deviate from standard pump gasoline (e.g., E10).

Interchange Part Numbers

The TU424HP-2 represents an elite-tier drop-in solution for GM Truck Cab & Chassis owners seeking significant fuel delivery improvements with factory-level integration. This module utilizes a high-output turbine pump with an integral Venturi jet located at the pump inlet. This advanced design ensures the module bucket remains actively filled, preventing starvation during low-fuel levels or aggressive driving maneuvers.

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

GM truck platforms often utilize multiple different fuel module configurations for the same model year (e.g. Standard vs. Cab & Chassis). Searching by vehicle type and trim level is insufficient; the VIN is the ultimate "Go / No-Go" check for fitment.

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