Fueling Upgrades

Autotech is the premier manufacturer of fuel pump upgrades for the FSI engine because our kit offers the highest quality, solid engineering, and great value.

Our HPFP Kit can achieve flow rates 50% higher than the original pump, essentially removing pump limitations from the equation, even on high-end turbo upgrades.

Our HPFP kit continues to be the benchmark that imitators strive to reach. However, Autotech’s HPFP Kit is not easily duplicated.

There are many reasons why Autotech’s Kit is superior. Here are a few:

~Each piston (9.8mm) and cylinder in Autotech HPFP kit undergo high-precision grinding processes many times during their manufacture, ensuring that the most precise tolerances are maintained through the final step. Not the cheapest way to make them, but the best way.

~Each piston and cylinder are match-ground and serialized to ensure absolute precision and the utmost longevity.

~Autotech was the first to incorporate plasma DLC coating on HPFP components to reduce friction losses and increase performance. Others have tried to follow by adding a coating to their parts. However, the DLC process alone is not enough – it is not a cure for substandard precision – the parts must be engineered specifically for the process to take full advantage: Autotech’s are. The success we have in the field can attest to that.

~HPFP-specific mapping is now commonly available from tuners worldwide.

Tuners trust Autotech’s HPFP in their conversions and upgrades because it works, and works well.

Fits VW/Audi 2.0T FSI 2006-2008.5, MK6 Golf R, and some Mazdaspeed 3 & 6 models.

When a specific pressure is exceeded the pressure regulating valve allows fuel to escape from the high pressure fuel rail. If the pressure release valve has gone bad, then it can cause low fuel rail pressure which results in fault codes, lose of power, and a high risk of melting a piston within the engine . This Part is a great upgrade from your stock 2.0T pressure regulator valve which has an opening pressure of 130bar. With an opening pressure of 165bar you will be able to delivery more fuel to your 2.0T FSI engine giving the ability to make more horsepower. 

This is for big turbo applications mostly!

Description: Fuel injector. Each injector comes with new seals. This injector can be used as an upgrade on the EA113 2.0T motor, if you're running BIG power! These ones don't blow black smoke like the older version of the "RS4" injector, which has the same connector as the EA113 2.0T. These injectors have a different plug/connector, so we include a new connector and a short length of wire with each one - you will need to wire these in to your existing harness if you wan to use them on your EA113 2.0T. This is a "stage 3" injector

Application(s): 4.2 FSI, 4.0TFSI, found in the RS4, RS5, RS6, RS7, S6, S8, S7, & R8.

• OEM technology designed and developed for E85

Dual channel turbine design for maximum efficiency under high pressure and high temperature applications
Made in USA by TI Automotive (parent company of Walbro)

 All pumping components have been validated to OEM specifications for approved use in E85/flex fuel applications

100% Authentic & Genuine Walbro/ TI Automotive E85 Racing In tank 450 LPH high pressure fuel pump with installation kit

Walbro F90000267 internal E85 HP RACING fuel pump

Installation kit  ( fuel strainer, fuel hose, harness pigtail, 2 clamps, 2 wire connectors

The F90000267 requires modifications to system wiring, fuel lines and the fuel module, and should be professionally installed.

The innovative design of the DCSS 39/50 features a single impeller with two parallel rows of turbine blades.
Designed for high performance engines exceeding 500hp.
Designed for E85 or Gasoline applications.
The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge.
This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that’s 20 percent higher than conventional pumps.

Application(s): 2.0 TFSI engines as found in the TT, TT-S and S3, and MK6 Golf R. They are an upgrade injector for the MK5 Golf GTI, 8P A3, and Octavia vRS. If you're not sure if this part will fit your vehicle, please send us a message and we can help figure it out.

Description: OEM fuel injector. New seals are included, so you don't need the seal kit.

Fuel injectors do exactly what their name suggests, as they deliver fuel into an engine's combustion chambers to be burned. Fuel injectors can cause a whole host of problems that can lead to major engine damage if not diagnosed and replaced or repaired as soon as possible.

A dirty fuel injector can cause fuel line problems such as misfiring, hard starting, stalling and hesitation. If you are hearing other noises, such as clanging or high idling, you might want to check other areas of your fuel system.

Introduction:
As many of you know, the fuel system for the 2.0T FSI platform is composed of two separate systems: the high pressure system (50-130bar), and the low pressure system (3-5bar). While, the limitations of high pressure fuel delivery have been eliminated by varies products, The Low pressure system has been ignored!

Through our research and development here at USP Motorsports, we were able to determine that the low pressure fuel system is nearly maxed out when producing around 350whp, running an a/f ratio between 11.0:1 – 11.5:1. This limitation is a result of the in-tank fuel pump being maxed out. By replacing the factory in-tank fuel pump with an APR in-tank fuel pump, the low pressure fuel system sits on its limits at around 400whp, while still maintaining the same a/f ratio mentioned above.

Developing a low pressure fuel system to work properly with the complicated components and electronics of the 2.0T FSI was no easy task. The in-tank fuel pump that runs the FSI does not function like a traditional fuel pump. Meaning, the fuel pump does not always receive a full 12volt signal while the car is running like a traditional fuel pump does. Instead, the ECM controls the fuel pump through a Pulse-Width Modulated signal (PWM). This quickly ruled out the ability to add an inline fuel pump. Other options were explored but, adding a secondary in-tank fuel pump was the end result.

Function:
The main purpose of the USP Motorsports auxiliary fuel system is to provide enough fuel flow to the high pressure fuel pump to support 400+ horsepower safely. This was done by incorporating a secondary in-tank fuel pump that alone can support 600 horsepower. However, incorporating a secondary in-tank fuel pump by itself will not function properly as the FSI low pressure fuel system is return-less. To combat this issue USP Motorsports created a load-based fuel pump controller. The result is the secondary fuel pump only being turned on when it is needed.


This system is estimated to be good for around 700 wheel horsepower and is the same system used on our in-house MK5 GTI which produces 605whp
