Need's to be a STICKY
I have an A6, I wish you had posted this a year or so ago.
I did mine without dropping the craddle, it was a PITA, I had to walk away several times, but it worked, this write up would have helped understand some of the mystery
Great Job

Thanks for the kudos guys. This job is well within the scope of many do-it-yourself types and having photos to understand what you are dealing with before diving in raises the chance of success and lowers the WTF factor!

Have you been using the Z06 part number 19133441?
I ask as that number now cross references to 19149687 which has been the standard pump in 2010 and 2011 cars (excl. ZR1) according to the GM parts catalogs.
I called Edelbrock to question this as to why they still include a pump in their 1591 kit if the newer cars already had the same pump as a Z06 and if the old part number is now shipping as the *9687 part.
I received a call back a while later stating that Callaway, not GM, said that the pumps were different even in the later cars and that they needed to be swapped because GM was wrong in their catalogs or still putting lesser pumps in at the factory.
Has anyone here really pushed on a '10-'11 pump to see if it is possibly the same pump and not in need of an immediate change? Maybe some pictures of a '10-'11 pump directly beside the "Z06" pump to see if they share the same numbers on their parts or have physical differences?

I have not dropped the tank on a 2010+ car yet to see if the scenario is the same but I recall a forum member some time back..."MidnightMagnum" I think, that went through this with his 2010 Grand Sport and I remember he discovered the same thing as I found with my 2009...the part number of his original factory pump was different than the Z06 pump he replaced it with.
I think this needs more investigation but the Callaway comment seems to fit with what I found.
Here is the thread from last year on the issue.... http://forums.corvetteforum.com/c6-f...-the-same.html
