Alpha STC electric pump vs replace mechanical pump

The joys of owning a certificated aircraft! The mechanical pump is legal, and an STC makes the electric pump legal, but both together are not, unless you can get a field approval, and good luck with that!

Good to hear!

I still have the mechanical pump, but if/when the time comes I'll go with the electric one. One thing about the electric pump is that in most aircraft the electric fuel pump is only used during critical phases of flight, while on the coupe it operates continuously. I wonder how that will affect the longevity of the part? But I like the annunciator light on the panel that indicates empty wing tanks. Maybe someone reading this thread will know more about the pump being used and its robustness.
