Mike,

Here is the way I'll doing. I have the mechanical pump as a standby-pump on
the engine. The fuel is going through the pump  all the time in bypass, that
means all the fuel which is going through the mechanical pump goes via a
electrical valve back to the tank. In an electrical emergency, the valve
closes and the pump keeps the engine running up to ~2000m and ~55% power.
The fuel-pressure (Airbox pressure + 0,35 bar) is secured up to this
altitude and power setting. You can check the Airbox-Differential-pressure
with the new "uma"-gauge. www.umainstruments.com This instrument is the only
indicator for the fuel pressure on 914 engines which makes sense.

For checking the bypass-system the electrical pumps can switched off
momentarily after engine start.

Regards,

Gottfried

I am not sure whether it was Europa or not, but I heard that someone was
investigating putting the manual fuel pump on the 914 with electrical back
up pumps for the high demand situation.  Sounds like a good idea to me.

Does anyone know anything about it.

regards,

Mike
