Should be possible, though I'm curious how good the speed regulation
will be.  The diesel is a heavy vehicle for the amount of power it has,
and needs large throttle changes to maintain speed.  Also, the throttle
response curve is very different than a gas engine's -- more linear.

It might work but I'm unsure how well.  Vaccuum for the throttle servo
shouldn't be a problem, though, as long as you have a good vaccuum pump.
