Modification of the 2.0 TFSI EA113 engines far beyond OEM power levels requires an additional volume of high-pressure fuel to avoid "fuel cuts," especially in the midrange. In many cases, the factory fuel pump begins to suffer from pressure loss. The limitation of how much volume of fuel the high-pressure pump can flow is dependent upon the volume displaced by the pressurizing cylinder inside the pump. This upgrade replaces the internal parts responsible for pressure and volume of fuel that reaches your injectors to meet the demands that come with higher power.

The tolerances involved are critical, with the final surface finish on the piston inside the fuel pump being so precise that it can be damaged by touching with bare hands. The tolerances between the piston and the new sleeve the piston rides in can only be measured by a machine using air volumes to measure the part clearances to within microscopic levels. A CMM coordinate measuring machine is used here with success.

It comes with fully detailed instructions, including step-by-step fitting images, all necessary components, and a detailed install sheet to get the job done.
