For more information, visit www.P65warnings.ca.gov.The APR High Pressure Fuel Pump (MS100144) is a complete, brand-new fueling solution for VW and Audi 2.0T Gen 3 engines. This pump increases the maximum volume of fuel delivered by 37% over stock, making it an essential upgrade for Stage 3 turbo systems or any enthusiast running Ethanol (E85) blends. While the primary goal is not to increase rail pressure, the increased displacement ensures that the 200 bar target pressure remains steady during the high-demand, low-to-mid RPM range where factory pumps typically fail to keep up.
Every APR HPFP is built using a brand-new Hitachi OEM pump foundation. APR discards the factory internals in favor of high-grade, heat-treated stainless steel components machined to medical-grade tolerances as tight as .00004". The plunger features a Diamond-Like Coating (DLC) to minimize friction and wear. Unlike generic kits, APR includes a titanium retainer and a specifically weight-matched spring to prevent "pump float" at high RPMs, ensuring consistent performance throughout the entire power band.
Features:
- 37% Volume Increase: Provides a massive cushion of fuel volume to support larger turbochargers and high-flow injectors.
- E85 Compatible: Engineered to satisfy the high flow requirements of ethanol, which demands approximately 30-35% more volume than gasoline.
- Premium Internals: Features a DLC-coated piston and heat-treated bearing-grade stainless steel barrel and plunger.
- Titanium Retainer: High-strength, lightweight titanium ensures the assembly remains stable under extreme high-speed operation.
- Brand New OEM Unit: This part number includes a brand-new pump; no core or return of your old pump is required.
- Strict Testing Standards: Every pump is machine-tested and broken-in on APR’s specialized test rig before shipping to ensure zero leaks or solenoid failures.
- Extreme Precision: Machined to .00004" dimensional and .00005" geometrical tolerances for unmatched longevity.
