Denny You have to make sure the conduit or conduits feeding the Diesel Skid do not pass thur a classified area. If they do then they require to be treated as classified . This is done a lot where theres both Gas and Diesel pumps in the same area.

514.3 Classification of Locations. (A) Unclassified Locations. Where the authority having jurisdiction can satisfactorily determine that flammable liquids having a flash point below 38°C (100°F), such as gasoline, will not be handled, such location shall not be required to be classified.
Diesel has a flash point above 100°F and therefore the area is not required to be classified. Don

This is true although if on the same concrete island as a gas pump I treat them the same no matter the distance apart.
If they are close to each other the diesel dispenser may fall within the classified area for the gas dispenser and if so, then the electrical equipment within the classified area must meet the classification. Don
