It would be nice to have a mechanical fuel pump. One less drain on
the battery if the alternator goes dead.

Boy, it's gotta hurt to have that engine driven thru the firewall.

Actually, this can be a big deal.  I put a different V6 in my old 4WD Blazer,
and the motor had no place for a mech fuel pump.  I added an electric pump,
and Chevy called out an oil pressure switch for the pump.  Unfortunately,
it cost about $90, so I left it off, but I really don't like it.  Thinking
about
rigging up my own so than in event of an accident it won't keep pumping
fuel, possibly feeding/causing a fire.
