APR is pleased to present a high pressure fuel pump upgrade for the 2.5 TFSI.
APR is an OEM supplier of high pressure fueling components to VAG and has operated with a nearly perfect track record since the program's motorsport backed inception in 2006. With thousands of pumps sold yearly, APR has a wealth of knowledge and manufacturing techniques utilized in the production of critical fueling components with exceptional reliability.
The engine’s fueling system is very capable without modification, even at high power levels generated using APR’s Stage II+ ECU Upgrade and exhaust. However, APR’s Stage III Turbocharger System is capable of generating significantly more power and requires modification to high pressure fuel pump to keep up with fueling demands.
The APR High Pressure Fuel Pump addresses fueling needs and leaves plenty of headroom for safety and further increased power levels in the future. By increasing the pump’s internal capacity, the fueling system is capable of displacing a higher volume of fuel per minute at every RPM.
The key to APR’s 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 deeply quality controlled all within the USA with dimensional tolerances as tight as .0001” and geometric tolerances as tight as .00009”. 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 made of a 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 also of 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 spec’d spring.
