84' 190D diesel leak
 

Just bought an 84' 190D w/193K. Drove it from CO to AR, 1100 miles, ran beautifully. 39 mpg. I have noticed that I get a bit of diesel fuel leak off near the rear passenger wheel along the fender. I opened up the fuel door and there is diesel fuel on and around the cap and down along therear passenger side body of the car. I have over 3/4 of a tank of diesel. Just wondering if this is a common occurence. Perhaps the fuel is sloshing around in the tank and finding its way back up the pipe. I sure cant figure out any other place it might be coming from.
