A replaceable liner is for use with a storage tank hatch having a rim adapted to engage with a gasket within a cover and a neck extending vertically downward from the rim to define an aperture that provides access to an inside of the storage tank. The replaceable liner has a body having a rim-facing surface having a vertical cross sectional shape that conforms to a vertical cross sectional shape of the rim and a horizontal cross sectional shape that conforms to a perimeter of the rim, and a gasket facing surface opposite the rim facing surface. Sealant is provided along the rim facing surface of the body, the rim facing surface of the body adapted to engage the rim in a vapor-tight seal, and the gasket facing surface adapted to engage the gasket in a vapor-tight seal.
