Unfortunately, there's no accomplishing a project of this magnitude, without problems. No check engine light, but there is an ever so slight fuel leak from one of the fittings that was welded to the fuel rail. Already have that back off the car, cleaned all the fuel our if it with water, blown dry, and now sitting overnight.

Another issue is fuel pressure. The pump was upgraded to a unit from an SL55/65, but the Crossfire regulator/filter assembly remains. According to the parts manual, the 2003 CL55 AMG uses the same unit, and that unit sets the pressure at 55psi. The tuner tells me that it needs to be 86psi. When everything was apart, one thing not mentioned here was that the full fuel feed line was removed from the SRT6 parts car and added to this car. Not replacing the existing - adding. The reason for this was to add the capability of putting an adjustable fuel pressure regulator up in the engine bay, and use this additional feed line as a fuel return. The factory regulator/filter assembly will be replaced with a Ford type filter, as it should fit the stock location nicely, but eliminate the built in regulator. This will be accomplished tomorrow. Using the new fittings for the fuel rail loop, each side of the tail will now plumb over to the new adjustable regulator. I should have just set that up from the beginning, but the fuel rail wound up having to come off the car, anyway.

I thought I'd have video tonight, but it will have to wait until tomorrow.
