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 and the low pressure system. 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 testing 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.
What is included:
• High flow in-tank fuel pump
• Load-based fuel pump controller
• Preassembled fuel lines
• OEM Crimp style clamps
• Fuel distribution block
• Fuel Tank bulkhead assembly
• All wires, terminals, and connectors
•Detailed instructions

FAQs
What does this system do?
This system picks up where the factory low pressure fuel system left off. It provides the high pressure fuel pump with the needed fuel to achieve a high horsepower FSI motor.
How does this system work?
Your factory low pressure fuel system stays intact. The USP fuel system is added within the fuel tank to supplement the factory pump. The pump works off a load based controller so the added fuel is supplied only when it is needed.
How much power can this system handle?
This system has been tested on our in house GTI to 605whp and based on flow calculations should be good for 700whp.
How long does installation take?
Installation can be performed in around 2 hours.
I see other FSI cars making around 400whp without this, how is that possible?
There are a few ways. One way is that the car is running a dangerously high air fuel ratio. We have seen this on several local customers’ cars. We have seen a/f ratios as lean as 13:1 on pump gas under full boost. This is extremely dangerous and robs horsepower from the FSI motor. The second way is that they are simply making up the lack of fuel by using methanol injection. This can be extremely dangerous as well because most kits do not have a failsafe if one of the many components in the methanol kits stops functioning.
