No, I am not matching fuel pressure to boost pressure, but instead turning
up the fuel screw referenced
to boost.  That means, no boost, it acts like a normally fueled engine.  Get
into boost, you have an abundance
of air that can be burned, so you must add fuel for more power.   It will
only run away if you give it more fuel
than it can handle.  That can be tailored by spring resistance to the boost
aneroid.  It sounds complicated, but
it's really very simple.  Also, diesels will only run away if they are being
overfueled while there's no load.

Subject: Wierd application, hypothetical question. 

I'm just a lurker, but I can't help asking how the electronic or mechanical 
matching of fuel pressure to boost on a diesel will keep it from running 
away. Is this particualr engine air throttled?
