As many of you know, the fuel system for the 2.0T FSI/TSI 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 products such as the APR upgraded rail pump, 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. Our solution is a complete drop in replacement pump. Simply remove your factory fuel pump assembly and our unit drops right in.
The main purpose of the USP Motorsports fuel pump is to provide enough fuel flow to the high pressure fuel pump to support 400+ horsepower safely. This was done by utilizing an OEM quality fuel pump. Through R&D USP flow tested the factory fuel pump and found that it flows approximately 189 liters per hour. Our high flow drop in fuel pump replacement flows approximately 289 liters per hour, or around 50% more and has been tested in applications over 550whp.
This kit includes an upgraded OEM PWM Module also known as the fuel pump controller. This is highly recommended for non US spec as some of these models will experience intermittent issues with the pump due to voltage fluctuations. The controller included in this kit will solve those issues.
