[AT] Canola to diesel

[Ken Knierim]

Some of the early Mercury automatics (Cruisomatic, I believe) had 2
pumps as well and were also capable of being pull-started. There are
probably others. I would think this would be a rare thing today
though. Most cars are getting more reliable and less likely to "push a
wrecker" as folks used to call it. :)
