Mercedes: Relay Locations, fuel pump relay, 380sl


Question
I inquired a month or so back about my 1981 380SL issue and would like to follow up as to the locations of the following Items:

1)Fuel Pump Relay
2)Overload relay

I inquired with the Mercedez dealer and they seem to be clueless as to where these relays are located, I plan to order these parts from teh websites that you have suggested but wont do so till I find out where they are located. Your answers to the previous questions were very helpful. Thank you for your help.  

Answer
380SL of that vintage, the fuel pump relay should be behind the front passenger kick panel or behind the glove box and next to the speed controlller. It is bigger than the standard "ice cube" relays and has as many as 10 pins.
A bad fuel pump can melt one of the solder paths inside relay in half.
I would power the fuel pump directly and measure the current.
