1. A surfactant package for a water-in-hydrocarbon emulsion, comprising: a fatty acid component selected from the group consisting of neat oleic acid, neat linoleic acid and mixtures thereof;a fatty acid salt component comprising a salt of C16-C22 molecules, wherein said fatty acid salt component comprises a salt of a fatty acid and a water soluble amine;an alcohol component; anda salt of carboxylic acid, wherein said salt of carboxylic acid comprises a salt of C4-C12 molecules and is a salt of dodecanodioic acid, hexanodioic acid and combinations thereof, and wherein said fatty acid component and said fatty acid salt component are present in a ratio by volume to said salt of carboxylic acid of between about 3.33 and about 20. 2. The surfactant package of claim 1, wherein said water soluble amine is selected from the group consisting of monoethanolamine, ethylamine, diethylamine, triethylamine, n-propylamine, iso-propyl amine, diethanolamine, triethanolamine, ethylenediamine, isopropanolamine, 2-amino-2-methyl 1-propanol and mixtures thereof. 3. The surfactant package of claim 1, wherein said salt of said carboxylic acid is a salt of water soluble amine and said carboxylic acid. 4. The surfactant package of claim 3, wherein said water soluble amine is selected from the group consisting of monoethanolamine, ethylamine, diethylamine, triethylamine, n-propylamine, iso-propyl amine, diethanolamine, triethanolamine, ethylenediamine, isopropanolamine, 2-amino-2-methyl 1-propanol and mixtures thereof. 5. The surfactant package of claim 1, wherein said salt of carboxylic acid comprises carboxylate ions. 6. The surfactant package of claim 1, wherein said alcohol component comprises C4-C8 alcohols. 7. A water-in-hydrocarbon emulsion, comprising a water phase; a hydrocarbon phase; and a surfactant package, wherein said surfactant package comprises: a fatty acid component selected from the group consisting of neat oleic acid, neat linoleic acid and mixtures thereof;a fatty acid salt component comprising a salt of C16-C22 molecules, wherein said fatty acid salt component comprises a salt of a fatty acid and a water soluble amine;an alcohol component; anda salt of carboxylic acid, wherein said salt of carboxylic acid comprises a salt of C4-C12 molecules and is a salt of dodecanodioic acid, hexanodioic acid, and combinations thereof, wherein said fatty acid component and said fatty acid salt component are present in a ratio by volume to said salt of carboxylic acid of between about 3.33 and about 20, and wherein said emulsion contains said water phase in an amount between about 5% vol and about 20% vol based upon volume of said emulsion. 8. The emulsion of claim 7, wherein said water soluble amine is selected from the group consisting of monoethanolamine, ethylamine, diethylamine, triethylamine, n-propylamine, iso-propyl amine, diethanolamine, triethanolamine, ethylenediamine, isopropanolamine, 2-amino-2-methyl 1-propanol and mixtures thereof. 9. The emulsion of claim 7, wherein said salt of said carboxylic acid is a salt of water soluble amine and said carboxylic acid. 10. The emulsion of claim 9, wherein said water soluble amine is selected from the group consisting of monoethanolamine, ethylamine, diethylamine, triethylamine, n-propylamine, iso-propyl amine, diethanolamine, triethanolamine, ethylenediamine, isopropanolamine, 2-amino-2-methyl 1-propanol and mixtures thereof. 11. The emulsion of claim 7, wherein said salt of carboxylic acid comprises carboxylate ions. 12. The emulsion of claim 7, wherein said fatty acid component and said fatty acid salt component are present in an amount between about 3.0% vol and about 5.5% vol based upon volume of said emulsion. 13. The emulsion of claim 12, wherein said salt of said carboxylic acid is present in an amount between about 0.1% vol and about 1.2% vol based upon volume of said emulsion. 14. The emulsion of claim 13, wherein said emulsion has a ratio by volume of said water phase to said surfactant package of at least about 3.0. 15. The emulsion of claim 7, wherein said alcohol component comprises C4-C8 alcohol. 16. The emulsion of claim 7, wherein said hydrocarbon phase is Diesel fuel. 17. The emulsion of claim 7, wherein said emulsion is a stable microemulsion. 18. The surfactant package of claim 1, wherein the salt of carboxylic acid is a water soluble amine salt of dodecanodioic acid or hexanodioic acid. 19. The emulsion of claim 7, wherein the salt of carboxylic acid is a water soluble amine salt of dodecanodioic acid or hexanodioic acid.
