A few weeks ago while getting fuel i opened the water drain in the fuel filter like i always do every few thousand miles and then closed it. I started up and drove about 4 miles and pulled into a parking lot and idled like i always do for about 30 seconds till my EGT's come down. When i got out, there was a HUGE puddle of diesel fuel and a trail going out of the parking lot (I later followed it was a 4" wide streak for 4 MILES!). Even though the valve was snapped down, the valve was open. I had to lift the handle then snap it closed again, problem solved. Has that happened to anyone else in here? Is it a freak thing?, or should i bring it to DC (Nightmare)?
