Personally, I like to loosen the injector lines from the injectors, pull a
vacuum with a mity-vac on the shut off valve, and then crank the motor. If
the valve is seated correctly there should be no fuel coming from the pump.
If there is fuel, it should be a good amount, and then, yes, the valve is
installed wrong pushing the pump to a full rich mixture. While this is a
bit of labor, it allows a test before assuming a great risk. I used to do
this when learning the feel for a properly installed shut off valve.
When the valve is installed properly, before fastening it to the pump, you
should be able to pull the valve back and feel resistance from within the
pump due the valve being hooked into the pump lever inside. However, it can
be misleading if you have never done one before. Use extreme caution if
this is your only means of a test.
Should a run away occur, I hear CO2 works well. Personally, I would cut the
fuel supply line from the fuel filter housing to the injection pump with a
pair of wire cutters. A fuel line is far cheaper than a motor. Ensure you
know what line to cut if you should need to. It will be the line going from
the filter to the pump. On US spec the line runs to the pump facing the
fender, NOT the motor (that is the return line). On Euros the line goes in
to the nose of the pump. Your filter housing may have an arrow indicating
flow direction. Cutting the supply lines at the feed pump will be moot, as
it takes much longer to shut the motor down as all the fuel in the filter
will have to be consumed first. Rags may work, but you risk having one
ingested into the motor. Not a good thing.
Have fun.

I am hoping to receive my new shutoff valve from Rusty today/tomorrow
and am anxious to do the intallation.
Even though I fully understand that if you do this job right there is
no danger of destroying the engine due to a run-away, I want to be
prepared for a worst case scenerio.
Will someone please review for me the ways to quickly kill the engine
if disaster should strike? The ones that come to mind are firing a CO2
fire extinguisher into or stuffing a towel into the air cleaner.
Am I forgetting something that is easier?
