Bernhard10,
The 912UL engine needs the minimum fuel pressure specified by Rotax to
keep the float chambers at the correct level under normal flight
conditions. If it does not get the required fuel pressure and the float
level starts dropping, the engine will begin to lean out and will quit
when it no longer gets sufficient fuel. If this is a condition you want
to avoid (I certainly would) then this would be cause for "concern".
It is possible that your fuel pressure gauge is bad (unlikely in my
opinion). It is also possible that your mechanical fuel pump is bad
(more likely in my opinion). In either case I would check out both of
them before flying again.
It seems you are looking for someone to tell you this is not a problem
because you asked the same question on the Allegro List to which I
responded in a similar fashion. You may actually find someone to tell
you that. If you keep looking you probably will. Good luck with your
search for a Pollyanna. Fuel starvation for various reasons is the
number one cause of power loss accidents in the NTSB accident report
database.

Hi! Ira
No my engine is from Europa but as a replacement for the Jabiru 3300.
Although I did get the Firewall Forward Kit from Europa for a 914. It
has welded bungs with blanking caps on all exhaust pipes two caps of
which I've removed to put in Westach sensors.
Regards
Bob H G-PTAG

Bob,
Is your exhaust system the standard Europa FWF kit?
It is probably my retched memory playing tricks again, but I thought
the 914 routinely came with 2 EGT bungs.
The 912 kit of course comes with none from either Rotax or Europa
as Rotax does not require it. I have the two I welded in (2.75" or is
it 2.76") from the flange and would welcome two more if I had the
downtime to get them in.

Bernhard10 a crit :

Bernhard,
The 912S installation manual is really worth downloading from
http://www.kodiakbs.com
It states that the nominal fuel pressure is 0.3 bar, and should stay in
the 0.15-0.4 bar range (2.2-5.8 psi for the metrically challenged ;-)
The units are always printed on the gauge dial.
Regards,

Bernhard, one more point of fact added to Thom's response and that would
be you should go to www.Rotax.com<http://www.rotax.com/> and read the
service bulletin on the 912 fuel pump your model number may be in
question
