ProStar 500 Fuel Pump Kit - Dual 4BBL Carbs

The ProStar 500 Fuel Pump Kit - Dual 4BBL Carbs delivers the high-volume, consistent fuel delivery your dual four-barrel carburetor setup demands for maximum performance and reliability. Engineered by MAGNAFUEL/MAGNAFLOW, this kit addresses a critical need for serious enthusiasts building or restoring carbureted engines that require synchronized fuel flow to both carburetors without pressure fluctuations. Whether you're running a street cruiser, competition build, or classic muscle car, proper fuel system architecture separates reliable power delivery from starved carburetors and lean-out conditions.

The ProStar 500 operates on a proven dual-pump architecture designed specifically for carbureted applications requiring flow rates that single-pump systems cannot sustain under load. This kit integrates regulated pressure management to maintain stable fuel delivery across both 4-barrel carburetors, preventing fuel starvation during acceleration and sustained throttle use. The system's modular design allows for flexible installation configurations while maintaining precise pressure regulation—essential for carburetor tuning stability and avoiding fuel sloshing or vapor lock in high-heat engine bays. Quality construction and sealed components protect against contamination and vapor leaks that compromise cold-start performance and idle quality.

This fuel pump kit is ideal for builders and mechanics installing dual-carb setups on big-block or small-block platforms where factory fuel systems fall short of volumetric requirements. Installation suits custom fuel cell applications, in-tank configurations, and external-mounted pump scenarios common in hot rods and vintage race cars. Proper sizing ensures your carburetors receive uninterrupted fuel flow during sustained wide-open throttle conditions, eliminating hesitation and maintaining consistent air-fuel ratios. Compatibility with aftermarket fuel regulators and lines (sold separately) makes system integration straightforward for experienced builders.
