D4 Chassis Low Pressure Fuel Pump (A8 / S8 4.0T)

Upgrade your fueling system with our high-performance Low Pressure Fuel Pump (LPFP) solution for the D4 Audi A8 and S8 platforms.

At the heart of this system is a ProTec Cobra secondary pump, capable of supporting up to 1200whp on E85. On gasoline, the system will support approximately 1600hp, making it the ideal choice for high-power builds.

For installation, this LPFP requires our 4.0 TFSI Fuel Line Kit (or any -6AN engine bay line kit). The optional inline filter and AN fittings allow relocation of the factory filter to the firewall, maximizing space inside the fuel tank.

Key Features:

• Supports ~1600hp on gasoline and ~1200hp on ethanol (E85)

• Includes ProTec Cobra secondary pump for maximum flow

• Designed for direct integration with factory ECU calibration

• May require custom tuning for optimal fuel flow and fault-free operation (recommended tuners: LoadLogic, C4 Tuning, Slavov, GoRaceBox)

• Compatible with -6AN line kits for flexible installation

This is the ultimate fueling solution for serious 4.0T builds looking for reliability and the headroom to push power well beyond stock limits.

* Designed to work seamlessly with the factory ECU calibration, however may require custom tuning to run without faults and deliver the proper fuel flow/pressure under all conditions ANY COMPETANT TUNER (LOADLOGIC, C4TUNING, SLAVOV, GORACEBOX)
