ProTuner Motor Brush Card Assembly

The ProTuner Motor Brush Card Assembly is a precision fuel pump component engineered for high-performance fuel system tuning and engine optimization. This assembly serves as a critical internal component in MAGNAFUEL/MAGNAFLOW fuel systems, designed specifically for users who demand reliable, consistent fuel delivery in modified and performance vehicles. Whether you're building a street performance engine, a drag racing platform, or upgrading a stock fuel system, the ProTuner Motor Brush Card Assembly ensures your pump operates at peak efficiency and maintains the electrical integrity required for professional-grade fuel management.

This brush card assembly manages the electrical commutation and motor contact points within the fuel pump motor, directly affecting current delivery and motor longevity under sustained high-flow demand. The precision-engineered brush configuration minimizes electrical resistance while maximizing contact surface area, enabling stable voltage delivery across a range of fuel pump speeds and system pressures. Constructed to OEM specifications, the ProTuner Motor Brush Card Assembly uses durable materials capable of withstanding the thermal cycling and electrical stress inherent in high-output fuel delivery systems, ensuring reliable performance in both naturally aspirated and forced-induction applications.

Mechanics and tuners working with MAGNAFUEL/MAGNAFLOW systems benefit from this assembly when servicing, rebuilding, or replacing worn internal motor components. Installation requires familiarity with fuel pump assembly procedures and attention to proper brush seating and electrical connection alignment. This component is essential for anyone maintaining or rebuilding a performance fuel pump system, particularly in applications where fuel system reliability is non-negotiable. The compact 3.3 x 0.7 x 5.4-inch assembly integrates seamlessly into existing MAGNAFUEL/MAGNAFLOW pump housings, making it an ideal replacement or upgrade component for serious enthusiasts.
