That's usually the case, but when I originally checked mine (had a hard start and rough idle, accompanied by black smoke from the tailpipes), I pulled the hose a few times for poops and giggles to see if different conditions created fuel in the line (checked it cold, after a hot soak, etc.) A couple of times (usually after a hot soak), fuel was present and pouring out, a few other times it seemed dry as a bone, but I still could smell the gas, (this seemed to happen more over-night, when I checked it in the morining). I guess it depends on the conditions, ambient temp, fuel quality, etc....the gas may possibly evaporate if it sits for a while. I played with mine for about a week before I finally got a chance to get to the dealer to get the part (about $60-$80, depending on what kind of deal you get)...they had it in stock too, and mentioned how they replace them quite often.
