Hi Allan, probably the stuck piston will be my pressure issue.
I am checking how to remove it safely
As for the seals, the ones needed for my primary pressure regulator (F 026 T03 010) will be, according to my FD 0438 100027 :
lower Oring = 2 430 210 036
larger Oring = 2 430 210 051

Ok Allan thanks. 2 shims would rise pressure with 0,4 bar, correct?
This would bring my pressure around 5,5 bar?

You 'll need to test if one or too shims will be correct ...

Ok Allan,I'll first try with one.
I managed to remove the piston, It was not really stuck because when I used a magnet to pull the piston, it came lose without any problems.

Allan,
fantastic news : after replacement of the O-rings and putting 1 extra shim, my system pressure = 5.8 Bar (84Psi)
One question, you provide me a 3rd O-ring which I do not know where it should be placed ?

Great news Gerrit !

For the other O ring , it's to be sure you have the good size .
Your fuel flow is ok , the pressure is good , now you just need to adjust the CO and idle .
Back to the road !!!

I received today your box with the bottles and parts !
Thank you !
