WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.The APR 2.0T FSI High Pressure Fuel Pump (MS100016) is an essential performance upgrade for the VAG EA113 engine platform. Designed to eliminate the primary fueling bottleneck of the FSI engine, this pump increases the maximum volume of fuel delivered by 41% over stock. This allows the direct injection system to maintain steady rail pressure during high-demand situations, such as mid-range acceleration on Stage 2+ or K04-turbocharged builds where the factory pump typically loses pressure.
Every APR HPFP is built using a brand-new, genuine Hitachi pump body and features internal components machined to aerospace-grade tolerances (as tight as .00004"). The internal plunger is crafted from heat-treated, bearing-grade stainless steel with a Diamond-Like Coating (DLC) for extreme surface hardness. Unlike "DIY" internal kits, APR units are fully assembled in a clean-room environment and machine-tested on a specialized rig to ensure seal integrity and solenoid function before shipping, protecting your engine's camshaft from potential damage.
Features:
- 41% Increase in Fuel Volume: Provides the necessary fueling headroom for high-horsepower setups, including Stage 2+ and Stage 3 builds.
- Precision Engineering: Machined to .00004" dimensional and .00005" geometrical tolerances for unmatched reliability.
- DLC Coated Piston: The diamond-like coating ensures exceptional surface hardness, minimizing friction and wear on the internal components.
- Rigorous Testing: Every pump is broken-in and validated on an APR test rig to ensure zero "dead on arrival" units and prevent camshaft damage.
- Upgraded Internals: Includes a weight-matched spring to prevent "pump float" at high RPM and replaces all internal seals.
- OEM Reliability: Built using brand-new factory Hitachi pump bodies and sensors to ensure perfect fitment and longevity.
- Motorsport Proven: Based on the same technology APR supplied to VAG for use in various factory-backed racing programs.

- (1) Fully Assembled and Tested APR High Pressure Fuel Pump
Important Maintenance Note:
The EA113 engine platform is known for factory cam follower wear. APR strictly recommends replacing your cam follower with a new OEM unit when installing this pump. If your camshaft or follower is already worn, the pump may not achieve its full pressure capacity. Regularly inspect the cam follower as part of your maintenance routine to prevent catastrophic pump and engine damage.
Note: Specific APR ECU software is required to maximize the performance gains from this pump and is available for most 2.0T FSI vehicles.
Warranty: This product is supported by a Manufacturer's Warranty. Note: Manufacturer warranty terms are subject to change.
