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.

Why This Pump:

A low pressure fuel pump, which varies from ~40-95psi, delivers fuel from the gas tank to the high pressure fuel pump.
Then the high pressure, camshaft driven pump pressurizes the fuel to upwards of 130bar (almost 1900psi!) in order to
spray fuel directly into the combustion chamber. Unfortunately on cars that have many modifications, the stock
fuel pump cannot flow enough volume of fuel to maintain the system pressure and the car suffers from the
familiar "fuel cut" that so many modified customers experience.

The limitation of how much volume of fuel the high pressure pump can flow is dependent upon the volume displaced by
the pressurizing cylinder inside the pump and the number of times the piston reciprocates inside that cylinder. Since the
high pressure pump is driven off of the engine camshaft by a three lobe cam the piston of the pump cycles at 1.5 times
the engine rpm. (Engine camshaft turns at one-half engine rpm multiplied by three for the number of lobes on the high
pressure cam lobe).

Due to this dependency on engine rpm for the high pressure fuel pump output volume, the FSI pump is capable of flowing
almost 370hp at 7000 rpm but only 158hp at 3000rpm. The graph above illustrates the maximum horsepower potential
of the stock fuel pump compared to the APR FSI fuel pump. Also on the graph are stock and APR Stage III horsepower
numbers. Clearly, the stock pump is insufficient for the output generated by this upgraded kit. The only way to address
this issue while maintaining a pump that fits in the stock location is to change the volume of the pump's internal
pressurization chamber.

Addressing The Issue:

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 Pump Construction:

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.

Note:  You can also send us your current fuel pump to us at HS Tuning to be rebuilt
