# APR 09-15 Audi TTS Quattro High Pressure Fuel Pump - No Rebuild The APR High Pressure Fuel Pump (HPFP) increases maximum volume of fuel the HPFP can deliver by 41% over stock! In doing so, the direct injection fueling system is capable of satisfying fueling requirements set forth by high horsepower setups. This is accomplished by increasing the displacement of the pump using high quality components to exacting tolerances.How the direct injection system works:A low pressure fuel pump (LPFP) in the fuel tank delivers fuel to the high pressure fuel pump (HPFP) at roughly 4 to 6 bar. Fuel pressure is then bumped up to a maximum of 110-130 bar, depending on factory parts, with the HPFP. Finally, high pressure fuel is delivered to the injectors, which spray directly into the cylinders.The problem:The volume of fuel the HPFP pump can displace is directly tied to the displacement of the pump (Internal bore size, and cam shaft dictated stroke), and engine speed. The pump is driven off of a three lobe cam shaft, and as such, the pump cycles at 1.5 times the engine speed. Even the factory K03 and K04 turbochargers are capable of taxing this system, especially in the mid to lower RPM range where fuel volume is lower.The APR solution:We dramatically increase the volume of fuel the HPFP can displace at every RPM by increasing the displacement of the HPFP. This is accomplished by increasing the bore diameter of the pump's internal pressurizing cylinder. It's important to understand, despite the name, a HPFP upgrade is not necessary designed to increase the engine's fuel rail pressure. The primary goal is to increase the volume of fuel available, which will keep fuel pressure steady even in the most demanding of situations!High quality components and extreme tolerances:The HPFP internals must be machined to extreme tolerances and installed in a clean environment or the pump can easily fail. Dimensional tolerances on the APR HPFP are as tight as .00004" and geometric tolerances are as tight as .00005". - Dramatically increases the volume of fuel displaced by the HPFP by 41% - Maintains higher pressures under demanding situations - Heat-treated bearing-grade stainless steel material - Fully machine tested and broken in before shipping - Upgraded and weight matched spring - .00004" dimensional tolerances - .00005" geometrical tolerances - New factory pump included - Fully rebuilt in house - Spring seals replaced - Supports big power - DLC coated piston This Part Fits: Year Make Model Submodel 2006-2008 Audi A3 Base 2005-2008 Audi A4 Base 2007-2008 Audi A4 Cabriolet 2005-2008 Audi A4 Quattro Avant 2005-2008 Audi A4 Quattro Base 2007-2008 Audi A4 Quattro Cabriolet 2008-2009 Audi TT Base 2009-2015 Audi TTS Quattro Base 2007 Volkswagen Eos 2.0T 2007 Volkswagen Eos Base 2012-2015 Volkswagen Eos Executive 2015 Volkswagen Eos Final Edition 2008-2016 Volkswagen Eos Komfort 2008-2013 Volkswagen Eos Lux 2013-2014 Volkswagen Eos Sport 2008 Volkswagen Eos Turbo 2012-2013 Volkswagen Golf R Base 2006-2009 Volkswagen GTI Base 2007 Volkswagen GTI Fahrenheit 2006-2007 Volkswagen Jetta 2.0T 2006-2009 Volkswagen Jetta GLI 2009 Volkswagen Jetta SEL 2009-2010 Volkswagen Jetta TDI 2010 Volkswagen Jetta TDI Cup Edition 2008-2010 Volkswagen Jetta Wolfsburg Edition 2006-2007 Volkswagen Passat 2.0T 2008-2010 Volkswagen Passat Komfort 2008 Volkswagen Passat Lux 2008 Volkswagen Passat Turbo 2006-2007 Volkswagen Passat Value Edition 2007 Volkswagen Passat Wolfsburg Edition ## Details - **Price:** 2154.09 CAD - **Vendor:** APR - **Type:** Fuel Pumps ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 2154.09 CAD | In stock | ## Images - Photo - Primary - Photo - out of package - Photo - out of package - Photo - out of package - Photo - out of package --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/apr-09-15-audi-tts-quattro-high-pressure-fuel-pump-no-rebuild) > Updated: 2026-07-04
