Hi ARWEL,
What you are seeing is quite normal. If you have the nerve wait a few seconds
(and
I do mean seconds) without switching on the electric pump and you will find
the pressure indication recovers.
Read what Bud says. Only investigate further if the pressure does not recover or
anything else exciting happens.

Subject: Europa-List: Rotax 912ULS Low Fuel Pressure
Good Evening
I noticed something strange this evening asI was climbing out at full
power, when I got to about 1000ft, I switched the electric fuel pump off
and the fuel pressure dropped quite alarmingly from about 0.32bar to
below 0.2bar. When I noticed it, I immediately switched the electric
pump back on to restore the pressure. I then leveled off, reduced power
and flew a tight circuit back to land.
After landing, I monitored the pressure at various power levels (with
mechanical pump only) and saw the pressure was at around 0.3bar
continuously.
I have seen it posted on various forums that its 'one of those things'
and its nothing to worry about, but I do!!
I should also mention that Im seeing the pressure on a mechanical gauge
as opposed to an electrical display readout.
Has anybody else come accross this before and is it a real problem?
Thanks
Arwel
