Is there a way to reset the fuel pressure regulator on my 1983 380SL? I think that this is the item in question...it is a allen wrench adjustment, spring-loaded and accessible through an opening in the air-filter housing...in any event, this was moved around and my mileage has dropped way down, so I assume that I am somehow running the engine way too rich? Any advice would be greatly appreciated. Many thanks, Jeff
