Hi Frans,
The maximum consumption of a 914 is below 25 liters per hour. So whatever
pressure
loss occurs at 120 l/h is not important. The lower sensivity on the other
hand is important, because running idle will bring the consumption close to the
lower limit, and so introduce a fault in the fuel totaliser. The 914 has its
own fuel pressure regulator, to compensate fuel pressure to airbox pressure.
A slight drop in the feed line will be compensated for.
I had a button to remove the input from the return Flow sensor from the fuel
totaliser.
In the checklist procedure after engine start, pressing the button gave
me a reliable impression of the state of the filters, pumps and lines.
Regarards,
Jos Okhuijsen
