Where can I find the build date on my 89 300e? Also I'm getting a buzzing sound from the rear of the car (fuel pump?) I have went trhough previous posts and learned that the 89 124 has 2 fuel pumps...How could I figure out which one it is? And also where is the fuel filter located? I might as well change this out too!
