Jos,
The only measure of fuel pressure on the 914 that Rotax mentions is that the
px to the carbs should be 2-5psi over airbox px. That sort of dictates that
you should measure the airbox px and the carb inlet px (ie between the
regulator and the carb).
I have seen somewhere in the Rotax manuals a picture of a special banjo bolt
and hose end to pick off the regulator output px (but I can't remember
where!). I also have a very vague memory that this should only be taken from
one particular side of the regulator?????

Subject: Europa-List: 914: fuel over airbox pressure
Hi team,
Does the UMA transducer connect between the airbox and the carburettor feed
line or between the airbox and the fuel feed on the pressure regulator? In
other words: before or after the pressure regulator?
In the rotax doc an after pressure regulator setup is shown as a desired,
not supplied option, however i assume that it is more interesting to see a
warning about fuel pressure drop before the regulator runs out of pressure
to regulate :-)
Kind Regards,
Jos Okhuijsen
