It is done by setting the demand lever or electronic equivalent below
idle. You do NOT shut off fuel to the engine. If you do that then the hp
pump will make a nice vacuum in the intake parts and eventually suck in
air. If that happens starting the engine later will be great fun, even if
no gaskets and o-rings are sucked off their seats. Just shutting off the
fuel may work for very small engines. In general diesels absolutely hate
air or vacuum in the fuel system.
