M50x1.5 to AN6 High Pressure Fuel Pump (HPFP) Cap
For Audi / VW 2.0L TSI TFSI EA888 Gen 3 Engines
Upgrade your fuel system with the CNC Innovations HPFP Cap, precision CNC machined from a single piece of premium 6061-T6 billet aluminum for maximum strength, durability, and leak-free performance under high fuel pressures.
✅ Features:
• Fully billet CNC-machined construction from one-piece 6061-T6 aluminum alloy
• M50x1.5 thread designed specifically for EA888 Gen 3 HPFP applications
• AN6 (-6AN) outlet fitting size (9/16”-18 SAE thread)
• Corrosion-resistant and lightweight design
• Includes stainless steel round baffle plate
• Direct replacement for factory HPFP cap
🔹 Stainless Steel Baffle Plate Function
The supplied stainless steel round baffle plate helps regulate fuel flow and minimize turbulence inside the pump housing. Simply place the baffle plate inside the cap and secure the AN fitting in place. Once fuel pressure builds during operation, the plate will automatically position itself correctly within the assembly, ensuring optimal fuel distribution and consistent pump performance.
🔹 Why Upgrade?
This HPFP cap allows easy integration of AN fuel lines for custom fuel system setups, ethanol conversions, upgraded fueling solutions, and high-performance applications. The robust billet construction provides superior reliability compared to factory components while maintaining proper fuel flow characteristics.
