Our mechical fuel pump Fuel pump was just replaced as part of the 5 year rubber.
Less than 10 hrs on the new pump. Fuel pressure warning light has been flickering on and off since I got it back from annual.
On take off at about 700 agl I turned off the boost pump, and almost immideatly the fuel pressure warning light went on and the engine started to sputer and lost power. I turned the boost pump back on and the engine started to run normally again.
The mecahnic that did the work thought it was a fuel pulsation issue (SB OSB20-069).
Rotech believes its the pump but can't be sure until we check the entire fuel system.
Has anyone experienced a similar issue?
We want to make sure we properly diagnose the problem but it sure seems to be the pump.
Any thoughts would be helpful!

Re: Mechanical fuel pump LOST PRESSURE IN FLIGHT
What was the outcome? Haven't ever worked on the Rotax Diamonds, so I don't know the system. Certainly sounds like the mechanical pump is the problem.
