C200 W203 M271 5bar fuel pressure regulator
According to Kleemann M271 Performance Kit manual it is recommended to change fuel pressure regulator. I have smaller kompressor pulley already.
I know how to put this new regulator but as far as i know there is built-in ~4bar pressure regulator in fuel filter. So installing new one after fuel filter won't do it's job.
I think i need to remove stock fuel filter to one without pressure regulator.
Any suggestions? Which filter would be good for my car?
Thanks.

The M271 fuel injection system as fitted to the C Class sedan is different to the V6 models in that it has a booster/amplifier pump up front being charged by the in-tank pump via the filter which has a min 3.8 bar regulator. I do not understand why the SLK is any different but it does have a different fuel tank arrangement. V6 models run on a > 3.8 bar fuel rail.
I strongly recommend you discuss this with Kleeman. They should recommend/supply a suitable filter if needed.
Hopefully someone that has done the job will chip in.
