Modification of the 2.0T FSI engine far beyond OEM power levels requires an additional volume of high-pressure fuel especially in the midrange (3000-5000rpm) of the powerband.
*This part is a complete HPFP Fuel Pump *
*Requires APR engine management recalibration for flawless drivability*
Fuel Pump Potential:
In order to address the lack of fuel in the midrange, the APR FSI fuel pump increases the volume of fuel from the high pressure pump by over 40%.
Simplified, this is achieved by modifying some key internal parts within the pump.
- Changing these components requires precision machining of the new components with special surface treatments as well as enlarged, redesigned seals. Using inferior components on this critical part can lead to many problems from gasoline in the engine oil (from a bad seal) to complete engine failure (from a seized piston in the high pressure pump).
To give an idea of the tolerances involved, the final surface finish on the piston inside the fuel pump is so critical that it can be damaged by touching them with bare hands. The tolerances between the piston and the new barrel the piston rides in can only be measured by a multi-million dollar machine which uses air volumes to measure the part clearances to within microscopic levels.
The components used in the APR pump are also of a high caliber. The piston and barrel of the new pump are made of a certified and heat-treated bearing-grade stainless steel and have a special diamond like coating.
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.
Each APR pump starts out as a brand new OEM pump and is then modified with the new components by APR and undergoes a rigorous testing process on our high pressure fuel pump tester. Once a pump passes our standards it is serialized and shipped to the customer
- Flow rates 40% higher
- Race Tested
- Rigorous testing process on our high pressure fuel pump tester
