High-Pressure Fuel Pump (HPFP) Upgrades

One of the most important upgrades for high-output direct-injection engines is the high-pressure fuel pump. Dorch Engineering HPFP upgrades are designed to dramatically increase fuel flow while maintaining OEM-level integration and reliability.

• High-Flow HPFP Systems: Upgraded pumps can significantly increase fueling capacity to support larger turbochargers and higher boost levels.
• Plug-and-Play Fitment: Many Dorch pumps are designed as direct replacements with OEM-style connections and full engine control integration.
• High Horsepower Support: Some configurations can support extremely high output builds, exceeding 900–1100 wheel horsepower when paired with supporting modifications.

These upgrades are commonly used by enthusiasts pushing their vehicles beyond the limitations of the factory fuel system.

Flex Fuel & Ethanol Integration

Running ethanol blends like E50 or E85 often requires advanced monitoring and fueling control. Dorch Engineering offers flex fuel kits designed to seamlessly integrate ethanol monitoring into modern engine management systems.

• CAN-Based Flex Fuel Kits: These systems monitor ethanol content and allow the engine control unit to automatically adjust fueling and tuning.
• Plug-and-Play Integration: Many kits install directly into the OEM harness with no cutting or wiring modifications required.

This technology allows drivers to run varying ethanol blends without manually switching tunes.
