    Description

    Advanced Fuel Control. The Aeromotive FourX Return-Type Fuel Control System for 3 to 4-Pump Systems provides precise, stand-alone speed management for multiple high-power brushed fuel pumps. It utilizes pulse width modulation combined with a dedicated MAP sensor to dynamically adjust pump speed based on fuel demand, reducing heat generation and preventing vapor lock in return-type fuel systems, especially in forced induction applications.

    _x000D__x000D_

    Construction and Appearance. Constructed with high-quality cross-linked polyethylene wiring and UL94 rated components, the controller features OEM Delphi/Aptiv electrical connectors for secure and reliable connections. The compact unit is engineered to withstand harsh automotive environments, including over-temperature and short circuit conditions, ensuring long-lasting durability and consistent performance.

    _x000D__x000D_

    Installation. The installation process is straightforward with no drilling required, designed to integrate seamlessly with existing return-type fuel systems. It easily replaces systems that rely on mechanical switches and relays, simplifying fuel pump speed control without complex wiring.

    _x000D__x000D_

    Warranty. This system carries a one-year limited warranty against defects in materials and workmanship.

    _x000D__x000D_

    Application. This product is intended primarily for forced induction fuel systems with two to four brushed fuel pumps. Adaptations may be necessary depending on specific fuel system configurations.
