I acquired a 2004 TS that has a hose, about 3/8ths diameter, with a ragged end that is dangling in the air near the front of the engine. The hose is routed into a tube that traverses the driver's seat and ends near the fuel tank level gauge. Does anyone know what this hose is, it purpose, and if I should be concerned the end is dangling and not connected to anything. The fuel level gauge face is cloudy and not readable, needs replacing, which makes me wonder if the hose and level sensor cloudiness are in some way related.
