APR MS100016 FSI High Pressure Fuel Pump Audi and Volkswagen 2.0T FSI
The APR MS100016 High Pressure Fuel Pump (HPFP) for the 2.0T FSI engine increases available fuel volume which a tuned engine demands while under heavy load. The FSI fueling system operates to a maximum of 1,900 psi (130 bar),To generate these enormous pressures, the low pressure fuel pump supplies fuel to a cam driven and solenoid fired high pressure fuel pump which in turn supplies the injectors with fuel. The APR pump has increased internal capacity which displaces a higher volume of fuel per minute at every RPM.

APR MS100016 HPFP Manufacturing
The key to APRs reliability comes in part by use of extremely high grade materials and manufacturing techniques. The most critical components within the HPFP are the enlarged plunger and barrel. Each matched set is created using medical grade precision machining techniques with dimensional tolerances as tight as .0001". The plunger and barrel are created from certified and heat-treated bearing-grade stainless steel and undergo a special diamond like coating process for exceptional surfaces hardness and ultra reliable operation. The seals used in the pump are high-performance filled polymer with a high modulus spring to retain the seal forces throughout the life of the product. The cross section of the seal is a proprietary design to maintain integrity over many years of use. Finally, to prevent float associated with altering the plungers mass, APR supplies each unit with a properly matched spring.
APR MS100016 Pump Testing
All APR HPFPs are assembled in house under strict assembly guidelines to ensure ultimate reliability and accountability. After construction the APR fuel pump tester plays a critical role in APRs track record of success. The test stand allows each pump to undergo a critical initial break-in period after creation without risking first operation on a live engine. The stand simulates real world operating conditions while APRs production teams inspect the pump for leaks. Solenoid operation is verified while ensuring the pump is operating within its design specifications. Each pump is then serialized and shipped in a highly protective box to ensure safety during shipping.
