| Subject: | Re: Rotax 914 fuel pressure |
Roland, The only reasons I have come across for low fuel
pressure in my 914 are fuel running out in main tank
(sorted by switching over to reserve) or gunge in the
gascolator (particularly happens early on when the initial
tank debris has not been all cleared). Others have
rerported rubbish in the in line original filters if you
have retained them rather than getting a gascolator, and
someone had a ball of dog hairs blocking the main exit
from the tank. It is certainly worth getting to the bottom
of it. You can easily check fuel flow by disconnecting the
fuel pipe prior to the carbs and running it into a jug.
Best of luck, David Joyce, G-XSDJ

the fuel pressure should be measured comparing to the air box pressure with
a differential gauge that aircraft spruce sells and would urge you to
upgrade to, I really have never measured fuel pressure by it self but would
guess it to be 5-15 pounds good luck jim leedy

Subject: RotaxEngines-List: Rotax 914 fuel pressure
From: "Roland" <schmidtroland@web.de>
Fellow Rotax 914 Jockeys,
forgive me this odd question please.
I have my Europa stored in the trailer and was doing some avionic checks
when I
noticed the fuel pressure was almost nothing indicated on the conventional
Rotax
gauge with one pump running and only about 0,15 bar (not steady) with the
boost pump switched on. The lower red line on the gauge is 0,25 bar. I can
clearly
hear both pumps running.
I don't know the aircraft that well since I bought it last year and thus
cannot
recall if that value changed. I also haven't tried yet with the engine
running
but my last flight was completely uneventful.
I regard that as a vital question and would appreciate your opinion on
this item.
Do I have to worry?
Happy (rest) Easter.
Roland
