I notice the comment that High Pressure pumps draw 10 amps, not
necessarily so.  While those of higher flow capacity do seem to draw
10-12 or more amps, the ones I use, MSD EFI Pump Part 2225 are rated at
5.8 amps @ 12V giving 40 GPH flow at 45 PSI. So depending on the
robustness of your electrical system and battery you might want to
carefully compare the specifications of different EFI pumps, they vary
considerably in performance (and $$$$).

Very good idea Ed.

That 10 amps was purely an un-educated guess on my part.
Thanks for giving us that current drain information. If
any of you have different pumps it would be good if you chimed
in with the current drain info.

That is only 0.093 HP so a manual high pressure back up pump is even
more partical.
