Secondary air injection

Does anyone know the Mercedes part number for a 2005 SRT6 secondary fuel injection pump? I've gone through two of them in 80,000 miles.

If you are burning them out it may be because it is running all the time.
It will run all the time when the relay in the RCM gets the relay contacts welded together. Inspect the relay as shown in the RCM repair thread.

Here is a picture of a burnt relay.(click)
