Electric fuel pump failure - how big is the risk?
So there I was before engine start, but when I turned on the electric fuel pump, the amber fuel pressure warning light remained lit. I turned the electric pump off and on again, no change, the light remained. I could hear the pump working behind me, but it was "missing a beat" sometimes, wasn't as regular as it used to be.
Suspecting this might be a partial failure, membrane leakage for example, I gave the starter a try and the engine started up normally, with the fuel pressure warning light going off.
Realistically, how big is the risk flying such an airplane? Is there any known incident, where the failure of both the main and the electric fuel pump resulted in a complete engine failure and a forced landing?
We use the electric pump during take off and landing. And of course, in case the warning light comes on due to failure of the main pump operated by the engine itself.
