Rowland,
That is where I mounted my sensor. I have not identified any disadvantages.

Subject: Europa-List: where to locate fuel pressure sensor
--> <rowlandcarson@gmail.com>
I've not yet started the firewall-forward work, but am planning the fuel
system of my 912S installation as a whole while working on the fuselage
parts of it.
I'm intending to install a UMA fuel pressure sensor, and for it to be most
useful, it seems good to have it as close to the carburettors as possible.
The manual shows the fuel line coming from the mechanical pump first to the
starboard carb, then the port carb and finally exiting via the restrictor to
the return line, so the choices for positioning a pressure sensor takeoff
tee are (a) between pump & stbd carb, (b) between the 2 carbs, and (c)
between the port carb and the restrictor.
I notice in the current Kitplanes a picture of several engine-bay sensors
mounted on the firewall and the caption says:
"Sensors for (left to right) oil pressure, manifold pressure, and fuel
pressure should be mounted remotely on the firewall."
Presumably this recommendation is to isolate them from engine vibration &
heat. However, without adding a long extra piece of piping, the only one of
the 3 choices above that allows a firewall mount is (c) - between the port
carb and the restrictor.
Does anyone see a problem with this proposed arrangement?
If I'm barking up the wrong tree, where have others mounted fuel pressure
sensors?
in friendship
Rowland
