VIS Motorsport High Pressure Fuel Pump Upgrade Kit 2.0TFSi - EA113 - VISEA113S1
 
Modification of the 2.0TFSi 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 we see the factory fuel pump begin 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 that are responsible for pressure and volume of fuel that reaches your injectors to meet the demands that come for higher power.
 
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.
CMM coordinate measuring machine is a device for measuring the physical geometrical characteristics of an object and used here with success.
 
Features:
 
The piston has over than 55% - 75% area over OEM
 
The piston head is optimized for ideal fuel flow direction
 
Piston surface is hardened and heat treated in 3 different stages
 
Uses OEM-style spring keeper, not a higher rated one that will prematurely wear the cam follower
  
Even a standard stock or Stage 1 car will see benefits from running these internals. They can sustain easy 600 hp, over 175 bar if hardware setup allow!
 
Laser marked for better traceability and protecting from fake / replica products.
 
Pump housing O ring made of Viton
 
Not only does the upgrade increase the amount of fuel your high pressure fuel pump can deliver but it will also decrease the duty cycle of the N276 solenoid on your pump. Lowering the duty cycle of the N276 will extend the life of this solenoid, an item that commonly fails on these pumps but isn't available separately.
