The ProStar 500 Seal Kit (MP-4450-SK) by Magnaflow Fuel Systems is a precision rebuild component designed for fuel pump maintenance and restoration in high-performance and street vehicles. This kit effectively addresses the wear patterns that develop in electric fuel pump assemblies over time, ensuring reliable pressure delivery when original seals degrade.
The ProStar 500 Seal Kit includes factory-engineered elastomer seals and gasket materials that restore the internal compression and flow characteristics of your fuel pump module. The seals are precision-molded to OEM specifications, ensuring zero leakage at the pump inlet, outlet, and internal pressure relief circuits. Designed to withstand ethanol-blended fuels, these seals resist hardening from prolonged heat exposure.
Technicians and enthusiasts working on vintage fuel systems, addressing fuel pump noise, or recovering lost fuel pressure will find this kit essential for restoring pump longevity. Proper installation requires careful disassembly of the fuel pump assembly and methodical replacement of worn elastomers to prevent fuel vapor leaks and pressure loss under load.
