How much current does your fuel pump draw Ed?

  However, to answer your question, the pumps specs indicate they

draw 5.

5.8 amps at 12 volts.

Wow, that's 70 watts per pump!

Tracy, how much power (amps) does your EFI and ignition controller draw

(including

coils)?

This really makes me think twice about wanting to change from carburated

to EFI on

an all electrical airplane. Runtime on a 20 amp-hours battery with the

alternator

gone?

The EC2 itself only uses about .15A.  The pumps I have are rated as 8 A. Max
but the measured typical load during cruise conditions is only around 4A.
Total system load in emergengy mode (all non essential stuff off) is about
13 Amps.  I have just over an hour to find a place to land if the alternator
quits.  BTW,  it is nuts to fly one of these "electric airplanes" without an
alarm to warn of alternator failure.
