Great write up / how to do :) - Is this pump an absoulte must on a Stage 2 4bar FPR K03s Ibiza or is it optional depending how good / bad your original pump is already??? I'm considering K03s but not sure if this is needed to be done first?
 
Its not absolutely needed no unless like you said your pump is old and knackered.

Ok thanks for the clarification, so regardless of having a k03 or k03s the standard pump on stage2 is ok unless knackered. What I'm trying to ask I suppose, is if fitting a K03s would put more on the pump over the k03 on stage2...
