JB4 320i install - Flex Fuel Connector - is it needed?

[Alex0607]

I just ordered a JB4 for my 2012 F30 and was going through some install video when I realised for the 320 and 520 you are "required" to install the flex fuel connector which is a separator item. I don't believe I have this item ordered.

I understand the Flex Fuel is to allow the N20 engine to use fuel mixture with ethanol. If I don't use this type of fuel mixture, do I need to install this connector cable? I read someone did an install on their 320i without installing the connector and the car ran fine.

Thanks in advance.

Nevermind. Found out the current JB4 has the connector as part of the system. So all good.
