Hi guys, hope you all had a good holiday season...<BR><BR>The other day
after take off I noticed low fuel pressure (less then 2 psi)&nbsp;on&nbsp;my
gauge,&nbsp;but being the brave (and perhaps stupid) soul that I am
I&nbsp;carried on to my destination. Redline on my&nbsp;gauge is 2
psi.<BR>&nbsp;<BR>The engine ran fine for this 1.5 hour flight. The electric
fuel pump made no difference to the pressure indication. After departure
from my destination&nbsp;that evening, the pressure read 4-5 psi on the
ground (responding to the electric fuel pump) then&nbsp;, immediately after
take off&nbsp;hovered at 1 psi. As I climbed out&nbsp;to 7,000 feet the
pressure&nbsp;headed even further south (0.5 psi).&nbsp; I also
heard&nbsp;(?real or imagined)&nbsp;the engine hesitate for a nano second.
This happened 3 times. <BR><BR>I returned to the aerodrome 15 minutes after
departure as I thought it was the prudent thing to do (even though it meant
a 6 hour drive instead).<BR>On descent the fuel pressure returned to 4-5 psi
and the landing was uneventful.<BR><BR>I tried the electric fuel pump after
I shut down and the pressure pumped up to 6 psi no problems.<BR><BR>I have
over 300 hours in this airplane and on all flights&nbsp;have observed that
the fuel pressure normally sits at 2 psi, just above redline in the cruise,
but intermittently (and apparently spontaneously) wanders to 5psi before
returning to 2 psi.<BR><BR>Any one care to comment on potential probems or
reasons for this? Mine is a carburetted 0-320.<BR><BR>In the interim, I have
decided not to fly until it is checked out be a LAME.<BR><BR><BR>Gerard O
Connell<BR>Melbourne, Australia<BR>VH-LPD (LNC2)<BR><BR><BR>
