    Description

    Advanced Fuel Control. The Aeromotive FourX Return-Type Fuel Control System for 3 to 4-Pump Systems is a comprehensive pulse width modulation controller kit designed to efficiently manage up to four high-power brushed fuel pumps. It modulates fuel pump speed using a stand-alone 2.5bar LSA/LS9 type MAP sensor to optimize fuel delivery while significantly reducing pump heat during low-demand conditions, which helps prevent vapor lock in high-performance forced induction engines.

    _x000D__x000D_

    Durable Construction And Materials. This system features a compact controller with a minimum continuous power rating of 110 amps, built with UL94 rated components and all cross-linked polyethylene wiring. It includes OEM Delphi/Aptiv connectors for reliable electrical connections, ensuring durability under demanding automotive conditions.

    _x000D__x000D_

    Installation. Installation is straightforward with no drilling required, integrating easily into traditional return-style fuel plumbing systems. The controller replaces conventional relay and Hobb’s switch arrangements, simplifying high-flow fuel system setups.

    _x000D__x000D_

    Warranty. This product comes with a one-year limited warranty against defects in material and workmanship.

    _x000D__x000D_

    Application. Engineered specifically for forced induction fuel systems utilizing 3 to 4 brushed fuel pumps, the system fits universal applications with some adaptation. For naturally aspirated applications, please contact Aeromotive for guidance on suitability.
