This reminded me of an incident with my bus, which is a warning to anyone
with a Cis conversion.  I was opening the rear decklid and it slide forward
and droped into the opening.  I saw a puff of smoke before I could lift the
door out of the engine bay.  What had happened, was the door, being made of
steel, conducted electricity from the Alt to one of the s.s. braided fuel
lines.  The line that was touched conducted juice to two other lines, all
three were instantly heated several hundred degrees.  Instant melted
plastic underneath the braid.  As the plastic cooled I started smelling
gas.  The residual pressure in the fuel lines had pushed the melted plastic
through the braid opening up many small holes for the gas to get out.  I
traced the point where the lid had made contact with 12V+ and it was the
top screw holding what looks like a voltage regulator on the back of the
alternator.  The main electrical wires had covers over the terminals, but
there was no indication that a screw which looks like it is simply holding
the regulator on would be hot.  If you have a Cis conversion or come to
think of it it doesn't matter which engine you have make sure that all
sources of 12V are insulated so that accidental contact with a conducting
object doesn't fry your bus.  In my case I saw the smoke and noticed what
had happened.  If I hadn't a finely atomized gas spray would have filled my
engine bay when I tried to drive the next time, poof.
