Hi Frank,
If you don't have the Rotax airbox you need to get one. There are other connections
that need to get made on this airbox.

Hi Frank,
The current install manual, Edition 2 Rev 0, page 103 describes these sensors.
The static sensor needs to pick up the pressure near the inlet to the turbo. In
my Europa the sensor is mounted on the firewall and a length of 4mm hose is
routed to near the air filter.
The airbox sensor has changed over the years. The current version has the sensor
mounted to the airbox. Older versions like mine and apparently yours, have
the sensor just connected to one of the 4mm hoses. You will need to cut the
hose and insert a tee. It's probably easiest to cut the hose between the airbox
and the fuel pressure regulator. You could also put a fitting into the threaded
boss on the airbox, near the port side. I have a airbox temp sensor there
that feeds my EFIS. The early install manuals specified water filters in the
circuits to sensors. The filters are just paper fuel filters. I've attached
the old install manual. Have a look at page 67.
While you are at it, fuel pressure specifications in the Operators Manual on a
914 is actually differential fuel pressure between the fuel pump and the airbox.
The OM actually says airbox press + 3.6 psi. Page 52 of the manual has a
little about this. UMA makes a differential pressure sensor that works well (P/N
1EU07D).
So I have a connection to the airbox that goes to the Rotax supplied airbox pressure
sensor and also to the airbox pressure side of my UMA differential fuel
pressure sensor.
Let me know if I can help further.
