Disclosed is a method of improving the effectiveness of an oxygen removal unit for a fuel supply system. The method includes contacting a tube bundle with a repair liquid at 20 to 40° C. for less than two hours. The tube bundle includes tubes having an air permeable, non-porous polymer layer with discontinuities. The repair liquid includes a solvent and a curable thermoset material. The curable thermoset material is deposited in the discontinuities of the air permeable, non-porous polymer layer and cured. Also disclosed is a fuel system oxygen removal unit including a tubular bundle formed of tubes having an air permeable, non-porous polymer layer disposed on a microporous support wherein the air permeable, non-porous polymer layer includes discrete segments of a cured thermoset material.
