First, Welcome to the forums.
Second, please avoid ALL CAPS. They are percieved as shouting and make reading posts difficult.
Third, thanks for asking. I haven't given this a great deal of thought before; but, years a go I would probably have simply said, "No." Things have changed a bit. The various original NFPA sources for Article 514 have changed.
While electrical area classification based on diesel alone is unnecessary, the emergency shutoff is based on diesel simply being a fuel. Neither Article 514 nor NFPA 30A, the current Art 514 source, specifically excludes considering diesel as a fuel.
Pesonally, I believe emergency controls/shutoffs for all "fuels" in Motor Fuel Dispensing Facilities are required by the appropriate Sections in 514.11.
