I have a 1993 300 SD. I go somewhere and return to my garage and park it go in the house then return to the garage a couple
of minutes later there is an odor of raw diesel fuel. After approx.
1/2 hr. to 45 min. the odor is totally gone. I have looked & felt of
all the lines ,connections, & crawled underneath but cannot find any leaks. I changed the filter also. Also I have looked while the car is idling. Does anybody have any ideas??? Thank you for any new ideas
