Welcome to 2CarPros.
First, I'm sorry to say that this vehicle isn't offered in the US, so my technical information is extremely limited. However, I will try my best to help.
The regulator on most vehicles is usually located either on the fuel rail or is part of the fuel module / pump assembly. Have you located it? If you have, is it possible for you to upload a picture of it so I can see exactly what you are dealing with?
Let me know.
Take care,
Joe
