03C127026D High Pressure Fuel Pump Direct OEM Replacement for VW Jetta Audi A3 1.4 TSI EA111 Engine Up to 200 Bar

A precision-engineered mechanical high-pressure fuel pump that generates the extreme fuel pressure (up to 35MPa) required for modern 1.2/1.4 TSI/TFSI direct injection engines. Converts camshaft rotation into high-pressure fuel delivery to the common rail, ensuring precise injection timing and optimal combustion for EA111 engines.

The High Pressure Fuel Pump (OEM Numbers: 03C127026D, 03C127026E, 03C127026C) is a premium-quality, direct replacement fuel system component engineered for the Volkswagen EA111 1.2 TSI and 1.4 TSI/TFSI engine families.

The pump is bolted directly to the cylinder head and driven by a dedicated camshaft lobe. As the cam lobe rotates, it compresses a spring-loaded piston inside the pump. The piston draws low-pressure fuel from the tank and compresses it to the high pressures required for common rail injection. A built-in fuel metering valve regulates the amount of fuel delivered to the rail based on ECU demand.

The EA111 engine family, including the 1.4 TSI (CAXA, CAXC, CAVA, CAVD) and 1.2 TSI (CBZA, CBZB) variants, was widely used in Volkswagen Group vehicles. The original Hitachi-sourced high-pressure pump is a known wear item that can fail due to internal piston or seal wear.
