APR Upgrade High Pressure fuel pump for 2.0T FSI
This is the brand new pre-built version of the APR Upgrade High Pressure fuel pump; with no reason to send your original pump back to us.

A low pressure fuel pump, which varies from ~40-95psi, delivers fuel from the gas tank to the high pressure fuel pump. Then the high pressure, camshaft driven pump pressurises the fuel to upwards of 130bar (almost 1900psi!) in order to spray fuel directly into the combustion chamber. Unfortunately on cars that have many modifications, the stock fuel pump cannot flow enough volume of fuel to maintain the system pressure and the car suffers from the familiar "fuel cut" that so many modified customers experience.

The limitation of how much volume of fuel the high pressure pump can flow is dependent upon the volume displaced by the pressurising cylinder inside the pump and the number of times the piston reciprocates inside that cylinder. Since the high pressure pump is driven off of the engine camshaft by a three lobe cam the piston of the pump cycles at 1.5 times the engine rpm. (Engine camshaft turns at one-half engine rpm multiplied by three for the number of lobes on the high pressure cam lobe).

Due to this dependency on engine rpm for the high pressure fuel pump output volume, the FSI pump is capable of flowing almost 370hp at 7000 rpm but only 158hp at 3000rpm. The graph below illustrates the maximum horsepower potential of the stock fuel pump compared to the APR FSI fuel pump. Also on the graph are stock and APR Stage III horsepower numbers. Clearly, the stock pump is insufficient for the output generated by this upgraded kit. The only way to address this issue while maintaining a pump that fits in the stock location is to change the volume of the pump's internal pressurisation chamber.

In order to address the lack of fuel in the midrange, the APR FSI fuel pump increases the volume of fuel from the high pressure pump by over 40%. Simplified, this is achieved by modifying some key internal parts within the pump. Changing these components requires precision machining of the new components with special surface treatments as well as enlarged, redesigned seals. Using inferior components on this critical part can lead to many problems from gasoline in the engine oil (from a bad seal) to complete engine failure (from a seized piston in the high pressure pump).

To give an idea of the tolerances involved, the final surface finish on the piston inside the fuel pump is so critical that it can be damaged by touching them with bare hands. The tolerances between the piston and the new barrel the piston rides in can only be measured by a multi-million dollar machine which uses air volumes to measure the part clearances to within microscopic levels.

Awesome GTI Delivery Information

BREXIT 2021 EUROPEAN TAXATION CHANGES:

For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods. If you are unsure of charges we recommend you should contact your local authorities ahead of placing your order.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
