Autotech – High Volume Fuel Pump Internal Kit for VW / Audi MK7 Gen 3 TSI / TFSI

Description

The Autotech High Volume Fuel Pump Internal Kit is a performance upgrade designed for EA888 Gen 3 TSI and TFSI engines. This kit replaces the internal components of the factory high-pressure fuel pump, increasing fuel delivery capacity to support higher horsepower applications and demanding performance setups.

The upgrade features a precision-engineered piston and cylinder assembly, manufactured with extremely tight tolerances to ensure consistent fuel pressure and long-term durability. Each piston and cylinder pair is match-ground and serialized to guarantee optimal performance and reliability under high load conditions.

By increasing fuel flow, the kit allows the engine to maintain proper air-fuel ratios when running higher boost levels, upgraded turbochargers or ethanol fuel blends. Even on stock tuning, the improved fuel delivery can result in measurable gains in horsepower and torque, while providing the headroom required for future performance upgrades.

This solution allows users to upgrade their existing high-pressure fuel pump without the need to purchase a complete new assembly, making it a cost-effective and efficient fuel system upgrade for tuned vehicles.
