VIS Motorsport HPFP Internals - 1.8T / 2.0T EA888 Gen 3
Modification of the 2.0T EA888 Gen3 to Stage 3 or above required additional volume of high-pressure fuel in order to eliminate 'fuel cut', especially in the mid-range.
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 that are responsible for pressure and volume of fuel that reaches your injectors to meet the demands that come with higher power levels.
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 sleeve the piston rides in can only be measured by a machine which uses air volumes to measure the part clearances to within microscopic levels.
