Kavlico Fuel pressure sensor position
Installing a 912 ULS into 601 HD, will have Dynon Skyview for EFIS. Looking at the Dynon instructions for installation of the fuel pressure sensor they recommend physically attaching firewall, which is not an issue.
My question is where is the best place to "T" into the fuel delivery system to get accurate fuel pressure?
I have fuel selector in cockpit, FWF - Gaslolator, electric fuel pump, fuel filter then into mechanical fuel pump on the engine. Then splitting to both carbs and a return line with a restrictor installed. Could I fit the fuel pressure sensor in the return line?
Thanks.

The general wisdom on the 912iS is to place the sensor just before the fuel filter. If your average fuel pressure rises over days/weeks/months, or is suddenly a bit higher one day, it's a potentially useful warning that your filter is likely becoming clogged.
Not sure what this means for a ULS install, but the idea might help narrow down your options.

As I remember there is a connection possibility in the fuel distributer block where the orifice sits. I did it like that.
