Hello All;

I have a 1989 420 SEL which has developed a problem with starting. When you turn on the ignition you can hear the fuel pump prime itself, then when you crank the car it takes a relatively long time to start and when it does start it runs very rough for several seconds and then the problem clears up. This can happen if the car is cold or even when it is hot. Usually if you start the car and run it for a while and shut it off and go back to it in a few minutes it starts just fine.

I have been told that this is most likely the fuel accumulator. My questions are where is the accumulator and are there any "tricks of the trade" to know when replacing?

Thank-you in advance for guidance.
