Inspected vehicle for customer concern. Found fuel residue on top of fuel tank. Removed rear seat and access panels. Found sealant on passenger side of tank is not air tight and is allowing fuel to escape tank, especially when tank is full. Removed previously installed cover and cleaned sealant from tank, cover, and mounting plate. Cut new gasket material for use between mounting plate and tank, and between tank and cover. Used seal grey fuel resistant gasket maker to seal both sides of both gaskets. Let sealer cure before torquing all hardware to full spec.
