An electrical driven vacuum pump totally defeats the purpose of
a vacuum system.
With the reliability of alternators and batteries being what it
is, one could go all electric with redundant alternators (the
expensive solution) or redundant batteries (and have at least
half an hour of fuel injected operation before battery died to
get on the ground).  Either one could probably be had for the
price of installing and maintaining a vacuum system.  As for a
simple, cheap vacuum system, one might look at an automotive
smog pump.  There are small ones, they are much more reliable
than the aviation systems and can be had for chump change at the
local wreck yard.  But why bother with all that plumbing?
Just a theory ... Jim S.
