TGK Motorsport High Pressure Fuel Pump Seal Rebuild Kit - Mazda MZR DISI

The TGK Motorsport HPFP Seal Rebuild Kit is designed to fix factory leaks, replace torn seals from HPFP upgrades,and restore fuel system integrity. Whether you're performing preventative maintenance or upgrading your fuel system, this kit ensures optimal HPFP operation and long-term reliability.

Over time, the factory high-pressure fuel pump (HPFP) Base seal in direct injection engines degrade, leading to fuel leaks, pressure loss, and cold start issues. Additionally, upgrading to larger HPFP pistons—a common modification for high-performance and ethanol (E85) tuning—can over stress and tear the OEM seal, allowing fuel to bypass the seal and mix with engine oil.

• Fixes Common Factory HPFP Leaks - Direct replacement for failing OEM seals that cause fuel seepage and pressure drops.

• Prevents HPFP Upgrade Seal Tearing - Reinforced seals withstand increased pressure from larger piston kits and performance modifications.

• Molybdenum Disulfide Seal Technology - Enhanced durability with superior friction resistance and improved longevity under extreme conditions.

• Restores Fuel Pressure & Reliability - Prevents fuel seepage, pressure drops, and cold start issues for consistent performance.

• Performance & Maintenance Solution - Ideal for both daily-driven vehicles and high-horsepower builds requiring reliable fuel delivery.
  
  
• Cost-Effective Alternative - Saves time and money compared to full pump replacement when housing and internals are in good condition.
