APR High Pressure Fuel Pump for the 2.5T FSI engine.
These are a requirement when doing a Stage 3 or Big turbo conversion on the 2.5TFSI engines.

- OUTRIGHT PURCHASE
This brand new fuel pump does not require any return for your old unit.

APR is pleased to present a high pressure fuel pump upgrade for the 2.5 TFSI.

APR is a Tier-One OEM supplier of high pressure fueling components to VAG and has operated with a nearly perfect tract 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.

In the early 2000's, VAG began supplying engines with a new direct injection technology known as FSI. Unlike conventional engines of the past, fuel is sprayed directly into the cylinders under extreme pressure resulting in increased power with lower consumption rates and fewer emissions. The technology has spread across VAG's entire lineup of modern gasoline engines and is present in the 2.5 TFSI.

The engine's fueling system operates to a maximum of 2,100 psi (145 bar) of pressure to correctly spray and atomize fuel directly into the engine's cylinders. This is contrast to multi port injection vehicles of the past which typically operated around 40-60 PSI and were driven off of a low pressure fuel pump. To generate these enormous pressures, the 2.5 TFSI's variable 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.

A three-lobe cam located on the exhaust camshaft drives the 2.5 TFSI's Hitachi Generation III high pressure fuel pump. As engine speed increases, so does the pump's ability to displace a greater volume of fuel per minute. The maximum volume the pump can deliver per revolution on the three-lobe cam is dictated by the stroke length from the cam lobe's lift and bore diameter of the pump's internal pressurizing cylinder. It's important to understand, despite the name, APR's High Pressure Fuel Pump upgrade is not necessarily designed to increase the engine's fuel rail pressure. The primary goal is to increase the volume of available fuel.

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.
