I left the cowls for the time being and decided to install the fuel flow transducer. Of the three install possibilities, I ruled out the two firewall forward as I couldn't find a correct position.
The third solution is to install the transducer in the cockpit, after the boost pump. This has its own problems as it is very cramped under the pump cover.
This website showed an elegant solution I decided to implement.
I just needed quite a lot of time to translate the pictures into an assembly I was satisfied with.
This will be the transducer's final position.



This is the transducer on its mounting bracket that will get riveted to the fuel pump support bracket.
The outlet fits just under the front cover.



Then a few tubings need to be redone. In the background is the transducer's inlet tubing, before it was running along the floor.



The filter outlet tubing needs also to be redone as it was running exactly where the transducer is now.
