Seal Kit for QuickStar 275/300

The Seal Kit for QuickStar 275/300 is a factory-engineered rebuild component designed for Magnafuel QuickStar electric fuel pumps operating in the 275 and 300 GPH classes. Built for mechanics and performance enthusiasts who demand reliability in high-flow fuel delivery systems, this seal kit addresses the inevitable wear that occurs in electric fuel pump assemblies over thousands of operating hours. Whether you're maintaining a carbureted hot rod, restoring a vintage muscle car, or servicing a modern EFI engine conversion, a complete seal refresh prevents fuel leaks, maintains system pressure integrity, and extends pump life significantly.

This rebuild kit contains precision-molded elastomer seals that form critical pressure boundaries within the QuickStar pump housing. Over time, thermal cycling, fuel chemistry exposure, and pressure cycling cause original seals to harden and lose their elastic recovery, leading to internal leakage and drop in delivery pressure. The replacement seals in this kit are engineered to OEM specifications using materials compatible with modern ethanol-blended gasoline and traditional fuel stocks alike. Proper seal installation restores the pump's ability to maintain rated flow and pressure across the entire RPM range, critical for carburetor bowl fill speed or fuel-injection system consistency.

Technicians performing in-tank or external pump service on Magnafuel QuickStar 275/300 units will find this kit essential for professional-grade rebuilds. The compact, lightweight package (0.02 lbs) contains all seals needed for a complete disassembly and reassembly without additional sourcing. Installation requires basic mechanical competency and familiarity with fuel system work—detailed Magnafuel documentation and online rebuild guides are widely available for step-by-step reference. Compatibility is exact for QuickStar 275 and 300 GPH pumps; verify your pump model before ordering to ensure proper fit and function.
