Variable Speed Fuel Pump Module Contr Spur 3.5

The Variable Speed Fuel Pump Module Controller Spur 3.5 from Aeromotive is a professional-grade electric fuel pump system engineered for high-performance and custom automotive applications. This in-tank pump module delivers precise fuel flow control and is ideal for builders and enthusiasts seeking adjustable fuel delivery matched to their engine's specific demands. The integrated speed controller enables real-time tuning without external components, making it a compact solution for fuel system upgrades on vehicles running E85, gasoline, or blended fuels.

This module operates at variable speed, allowing you to dial in fuel pressure and flow based on engine load and fuel composition. At 40 psi, the pump delivers 1700 lb/hr of fuel, sufficient for high-displacement and forced-induction engines. The unit features dual AN fittings—a 12 AN female O-ring inlet and 10 AN female O-ring outlet—ensuring leak-free connections to quality fuel system components. The included speed controller regulates pump voltage dynamically, reducing heat generation, electrical stress, and fuel system wear while optimizing fuel economy and engine response.

This fuel pump module is best suited for street rods, race cars, engine swaps, and turbocharged or supercharged builds where precise fuel delivery is critical. Installation occurs inside the fuel tank, preserving underbody aesthetics and engine bay space. The black finish resists corrosion in the fuel tank environment. Compatibility spans E85 and conventional gasoline applications, making it versatile for alternative fuel projects. Proper fuel line sizing and regulator configuration are essential; consult system pressure and flow requirements for your specific engine displacement and boost level to ensure optimal performance.
