I ordered a new fuel level sender (the driver's side suction pump). When I replaced my sway bars I noticed wetness on the driver's side of the fuel tank and a faint fuel smell. I discovered a crack on the topside (a plastic protrusion on the lid, that's not the hose attachment) of the fuel level sender suction pump. Strange. Oh well, parts on the way.
I'm glad I swapped the sway bars, otherwise I wouldn't have discovered it and would have continued to drive with a fuel leak.
