 |
|
I use the electric pump to charge the fuel system for startup, then
shut it off until after runup. That way I can confirm that the mechanical
pump is working. During my pre takeoff checklist, I turn on the electric
pump and monitor the fuel pressure on the EIS to make sure it bumps up a
1/2 psi or so. This confirms that the electric pump is working as well.
Once to cruise altitude, the electric pump comes off and is turned back on
for landing or switching tanks. I hope I didn't alarm folks with the vapor
lock issue. I just afirms the need for a backup fuel pump and the
importance of a pre takeoff and pre landing checklist that gets used
everytime.
