Hi there,
To make it even simpler I fitted a fuel pressure regulator which cost is 45....

Hi Richard
I have been watching this problem for some time and for what its worth I would
fit a fuel pressure gauge if you haven't already and then adjust the pressure
by increasing the size/diameter of the metering hole in the return line. The
main
problem [if you can call it that] is that the Rotax engine is very efficient
and uses very little fuel so the carburettor jetting is very fine which in
turn increases the danger of blockage. It sounds to me that Rotax have sourced
a pump that is capable of delivering a much greater amount of fuel than its
predecessor
and is overwhelming the carburettor float valve.

Thank you for your reply. Yes I agree with you totally and understand the
issue.
I was just wanted to know if anyone had had any problems with the new
replacement
pumps? I'm satisfied with the pressure I have on my aircraft at a new 5.8
psi (4 bar) MAX, as this was the maximum limit with the old pump.
the new max limit is 7.2 psi (5 bar) and can not reached, this dew to the return
to the tank (unless it gets blocked)
I did read the info in the LAA Magazine which give the thoughts of LAA
engineering
very well explained.
I can see this subject coming up for discussion again, as eventual all
engines
will require the new pump, and it is included in the 5 year rubber replacement
and will need to be completed eventual.
As my engine falls within the less than 5 years old and has just go into
service,
I decided it was a good move to fit the FREE replacement.
