the CH750 fuel system was done in 2012 as per the existing 912iS Installation Manual, before the 1-bar checkvalve and bypass restrictor were introduced. see attached.
an upgrade kit is in the works.
The restrictor was installed long before it was published in the installation manual and it should be after the fine-filter, otherwise it can become plugged from contamination. the function is exactly the same in either position so I don't know why the drawing shows it before the fine-filter. I will try and find out the reasoning and report back to the forum.
