Kraftstoffdruckregler von Reichard-Motorsport??

[Oliver]

So you didn´t understand what Ulli did write. Due to a too lean adjustment of the LPG, the lambda adaptation adds too much when running on fuel which leads to that high fuel consumption.
But if you still are thinking the fuel pressure regulator is the bad guy, I would recommend to check the fuel pressure with an external gauge.

It should be 3.5bar against atomspheric pressure with a returnless fuell system (regulator in the tank). You can see the pressure regulator in the first picture at the bottom of the pump.

Another question: Do you really see when running on LPG? Not that you run more on petrol then you are expecting....
