I know I'm being "that guy" right now, but I did search quite a bit (I think I just suck at the search feature). I know the SRT-6 engine is shared with the SLK32 AMG (2001-2004?)...but is there a full list of the years and models of cars that the engine is shared with somewhere? Also what is the specific engine code?

The reason I ask is I've been doing a search trying to pick up the cheapest fuel pump and fuel filter and getting grief from Mercedes dealerships because "they can't look it up without the specific engine code"...which I know is bull...but...I'm just sick of dealing with it.
