I don't know how an improper installation causes a runaway engine. Maybe the shut off actuator plunger pushes the rack to full load. For me it has been sufficient to see the stop lever react when I apply vacuum to the newly installed actuator.

Yes, I think the bananas would work best.

I would also think that once the new shut off valve is installed , a quick test for proper actuation with the hand vac to verify should be enough.
If the hand vac draws and hold the stop lever down fully it would seem that the installation is correct - I can't see much more needed than that...

Yes, thanks for the links - It is getting old fast - having to open the hood to shut off the engine.
My luck, the hood release will fail before I replace the vacuum shut off valve.
