1. A gas storage tank comprising a structural outer layer, an internal liner layer, an annular boss having a flange section extended inside said tank and partially overlapped with a section of said internal liner layer, and a liquid sealant disposed directly between an overlapping portion of said internal liner layer section and said flange section of said annular boss to provide a gas-tight seal, wherein said liquid sealant is adapted to flow under the gas pressure in the tank and seal small gaps between said internal liner layer and said flange section of said annular boss. 2. The gas storage tank as set forth in claim 1, wherein said internal liner layer comprises polyethylene or aluminum, and said structural outer layer comprises one or more fibers and a fiber reinforcing resin composite. 3. The gas storage tank as set forth in claim 2, wherein said internal liner layer comprises a high density polyethylene and said one or more fibers comprises a continuous filament of carbon or glass fiber and said resin comprises an epoxy resin. 4. The gas storage tank as set forth in claim 1, wherein said internal liner layer has a Young's modulus between 0.2 and 2 giga-Pascal and said annular boss comprises aluminum or an aluminum alloy. 5. A gas storage tank comprising a structural outer layer, an internal liner layer, an annular boss having a flange section extended inside said tank and partially overlapped with a section of said internal liner layer, and a liquid sealant disposed directly between an overlapping portion of said internal liner layer section and said flange section of said annular boss to provide a gas-tight seal, wherein said liquid sealant is adapted to flow under the gas pressure in the tank and seal small gaps between said internal liner layer and said flange section of said annular boss, wherein said liquid sealant comprises a polymer resin and a volatile solvent, and said polymer resin is capable of thickening, hardening and sealing small gaps between said internal liner layer and said flange section of said annular boss when said volatile solvent evaporates due to gas leaks through said small gaps. 6. A gas storage tank comprising a structural outer layer, an internal liner layer, an annular boss having a flange section extended inside said tank and partially overlapped with a section of said internal liner layer, and a liquid sealant disposed directly between an overlapping portion of said internal liner layer section and said flange section of said annular boss to provide a gas-tight seal, wherein said liquid sealant is adapted to flow under the gas pressure in the tank and seal small gaps between said internal liner layer and said flange section of said annular boss, wherein said liquid sealant comprises at least one of fibers and particles suspended in a viscous liquid. 7. The gas storage tank as set forth in claim 6, wherein said fibers or particles have a dimension of 0.01 mm or greater. 8. The gas storage tank as set forth in claim 6, wherein said particles are inorganic particles or rubber particles. 9. A gas storage tank comprising a structural outer layer, an internal liner layer, an annular boss having a flange section extended inside said tank and partially overlapped with a section of said internal liner layer, and a liquid sealant disposed directly between an overlapping portion of said internal liner layer section and said flange section of said annular boss to provide a gas-tight seal, wherein said liquid sealant is adapted to flow under the gas pressure in the tank and seal small gaps between said internal liner layer and said flange section of said annular boss, wherein said liquid sealant comprises a liquid rubber having an ASTM D1646 Mooney viscosity of 30 to about 100 measured at 100° C. 10. The gas storage tank as set forth in claim 9, wherein said liquid sealant comprises a diene liquid rubber or a saturated hydrocarbon rubber. 11. The gas storage tank as set forth in claim 9, wherein said liquid rubber comprises at least one of polyisoprene, polybutadiene, styrene/isoprene/butadiene terpolymers, hydrogenated polybutadiene, styrene-butadiene copolymer, polychloroprene (neoprene), acrylonitrile-butadiene copolymer, ethylene-propylene-diene ter polymer (EPDM), ethylene-propylene copolymers, isobutylene based elastomers, halogenated butyle rubbers, brominated isobutylene-co-para-methylstyrene polymer and their derivatives. 12. A gas storage tank comprising a structural outer layer, an internal liner layer, an annular boss having a flange section extended inside said tank and partially overlapped with a section of said internal liner layer, and a liquid sealant disposed directly between an overlapping portion of said internal liner layer section and said flange section of said annular boss to provide a gas-tight seal, wherein the liquid sealant is adapted to flow to and fill-in gaps between the flange section of the annular boss and the internal liner layer, sealing existing or newly developed leaks.
