APR 19-26 Audi Q3 2.0T EA888 Gen 3 High Pressure Pump - No Rebuild

The primary goal is to increase the volume of fuel available, which will keep fuel pressure steady even in the most demanding of situations!High quality components and extreme tolerances:The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004" and geometric tolerances are as tight as .00005". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and the plunger undergoes a special diamond like coating process for exceptional surfaces hardness and ultra-reliable operation. To prevent float associated with altering the plunger's mass, APR supplies each unit with a properly specified spring. All necessary internal seals are replaced.Internal testing:All APR HPFPs are assembled in house under strict assembly guidelines. Each pump is then tested on our test rig to ensure the pumps operate as designed. This step is important for several reasons. It's critical in determining if a pump has a failure from incorrect install, a leaking seal, or a bad solenoid. Secondly, a seized pump on the vehicle at startup can cause damage to the engine's camshaft. By testing each pump, we all but eliminate these possibility.Proven track record:APR pioneered HPFP upgrades in the early days of VAG direct injection engines. Soon after, APR became an OEM supplier of HPFP and GDI components to VAG for use in various race cars, racing series, project cars, and concept vehicles.

The APR MS100144 High-Pressure Fuel Pump upgrade increases the volume of fuel displaced by the factory high-pressure fuel pump by 37 percent, helping maintain stable fuel pressure during demanding driving conditions. This upgrade is designed for select Audi and Volkswagen direct-injection 2.0T EA888 Gen 3 applications, including the Audi A3, A3 Quattro, S3, Q3, TT, and TTS, as well as the Volkswagen Arteon, Atlas, Atlas Cross Sport, Golf, Golf Alltrack, and GTI within the listed model years. Verify vehicle compatibility before installation.
APR manufactures the MS100144 using heat-treated, bearing-grade stainless steel components selected for durability and reliable operation. The plunger and barrel are machined to extremely tight dimensional and geometric tolerances, while the plunger receives a diamond-like carbon coating for enhanced surface hardness and wear resistance. A properly specified, weight-matched spring helps prevent plunger float, and all necessary internal seals are replaced during the rebuilding process. The package also includes a titanium retainer and a new OEM pump.
Each APR high-pressure fuel pump is assembled in-house under controlled procedures, then tested on a dedicated test rig and broken in before shipment. This testing helps identify installation-related issues, leaking seals, or solenoid problems before the pump reaches the vehicle, reducing the risk of startup-related damage to the engine camshaft. APR has extensive experience developing high-pressure fuel system upgrades and supplying fuel system components for demanding motorsport and performance applications.
This APR MS100144 pump is intended for off-road and racing use where applicable and is not CARB approved. Professional installation is recommended, along with careful adherence to the vehicle manufacturer’s fuel system service procedures. Confirm the exact engine code, vehicle year, and application before ordering.
