    I thought the factory pressure was 4 bar? I can't remember, might be 3, but I'm sure there are different fixed pressure regulators that fit the factory rail? Was this the reason for mentioning changing to an aftermarket regulator?
    The only thing I want to add is an electric pressure sender so I can mount an internal pressure gauge.
    Factory fuel pressure is typically 40 psi so closer to 3 bar.

        Actually I forgot to add on the 1 bar due to atmosphere so 40psi is closer to 4
