Diesel fuel cross-drop prevention kit

A diesel fuel cross-drop prevention kit comprising:

• a drop-elbow coupler;
• a storage-tank inlet tube;
• an at least one primary key slot;
• an at least one primary key protrusion;
• a retractable pull pin;
• the drop-elbow coupler comprises a female outlet end and a male inlet end;
• the primary key slot being positioned adjacent to the female outlet end;
• the primary key slot laterally traversing into the drop-elbow coupler from an internal surface of the drop-elbow coupler;
• the primary key slot traversing into the drop-elbow coupler from an outlet rim of the drop-elbow coupler;
• the primary key protrusion being externally positioned to the storage-tank inlet tube;
• the primary key protrusion being laterally connected to the storage-tank inlet tube;
• the storage-tank inlet tube being positioned coincident and within the female outlet end;
• the primary key protrusion being positioned within the primary key slot;
• the retractable pull pin being positioned offset from the female outlet end, along the drop-elbow coupler;
• the retractable pull pin being laterally integrated into the drop-elbow coupler;
• a hose;
• a gravity-drop tube fitting;
• an at least one secondary key slot;
• an at least one secondary key protrusion;
• the hose comprises a tubular body, a first female coupler tube, and a second female coupler tube;
• the first female coupler tube being terminally connected to the tubular body;
• the second female coupler tube being terminally connected to the tubular body, opposite the first female coupler tube;
• the secondary key protrusion being positioned external and adjacent to the gravity-drop tube fitting;
• the secondary key protrusion being laterally connected to the gravity-drop tube fitting, adjacent to an outlet rim of the gravity-drop tube fitting;
• the secondary key slot laterally traversing into the first female coupler tube from an internal surface of the first female coupler tube;
• the secondary key slot traversing into an inlet rim of the first female coupler tube, opposite the tubular body;
• the gravity-drop tube fitting being positioned offset to the drop-elbow coupler;
• the gravity-drop tube fitting being positioned within the first female coupler tube;
• the secondary key protrusion being positioned within the secondary key slot;
• and
• the male inlet end being positioned within the second female coupler tube.
