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.

Fuel Pump Components
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.
APR FSI pumps have been track tested since 2006 with several hundreds of thousands of miles of combined usage. 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.

Motorsports Development
When it comes to a critical component that can mean the difference between winning a race and not finishing at all, motorsport teams must use the best components available. Motorsport teams around the world have put the APR High Pressure Fuel Pump though brutal and demanding testing and have proven again and again the reliability and performance you can expect from each and every APR High Pressure Fuel Pump. The initial success of the R-GTI and APR's own motorsport team have lead other noteworthy teams around the world to rely on APR.
Beginning in 2007, APR Motorsport brutally tested the FSI High Pressure Fuel Pump for thousands of miles at high stress levels. All three race cars successfully completeted their first seasons without a single issue from the APR High Pressure Fuel Pump. The team continues to put each pump though the same brutal testing race after race.
