Thanks guys
If you aren't losing power, and aren't getting lean codes, I doubt your fuel pump is the issue.
Thanks guys

Anyway, took my C7 to the dealer for some routine maintenance and because the check engine light was coming on. To my utter horror, he told me that the fuel pump needed replacement and that doing one of them would cost me around $3600!!! And that I should do both of them because they have to disassemble a lot of the back end, torque tube, etc. and that that'd run me a total of $5600!!! I'm definitely no mechanic and I have read that they are very labor-intensive to replace but $5600 seems like highway robbery. Is this close to correct? Is this common?
Are there any other places/repair shops in the North San Diego area that may do this for a lot less money?
But alas the independent guy called to say he can't do the job because he lacks a tool required for it so I guess it's back to the dealer.
Did you ask him, assuming he has the tool, for a detailed estimate or at least, compare what GM said? It might be helpful to know how he got it so cheap.

Anyways, the car's back at the dealer and getting the work done. They said they saw evidence of a rodent chewing a hole into something and I told them to take a pic or otherwise document it so I can try submitting an insurance claim. Anybody have more info about that it'd be appreciated.
You're assuming I'm a mechanic and will look at the details and say "That's not right" or "I probably don't need this part/work done". But I'm not a mechanic and while I can question extreme prices (in fact that's exactly why I posted!) and learn if they are within reason by using the wisdom of people in this forum, a detailed list to me would probably look like the Perl code I'm working on right now to you. IOW You'd just look at it and say "Hmmm... well I guess so".

Again true. But I am not sure where else to begin. When I don't understand what it is, I might ask a totally disinterested party to explain. I might ask my buddy who is a mechanic why I am paying for X, Y or Z.
Sucks but at least you are sorting it out.
I voiced concern that I'd rather not have the factory installed drivetrain torn from my car and reinstalled at a dealer to fix the pump and asked if they were aware of another way. (I had previously researched this and knew for myself it was in fact possible)
The dealer admitted they have a mechanic that is able to do the repair in a fraction of the book time by removing the rear facia and a muffler to gain access to release the crossover tube and be able to drop the tank with the entire drivetrain still in the car.
Also, I know for a fact that if your arms aren't too thick it is possible to reach up and pinch the release tangs on the left crossover hose clamp without removing anything at all. Once the clamp is released there is just 1 bolt and a bracket atop the transmission to remove and you can pull the crossover hose out of the tank fitting with nothing but your hand by forcing it back into a S shaped bend. I know this because I tried it out for myself before calling the dealer and was able to release it. It takes some contorting and is uncomfortable, but do-able.
You may want to ask around and find a private mechanic that might be willing to do it using one of these alternative methods and charge you actual time instead of book time. It is not necessary to drop the driveline out of the car if the mechanic is willing to get creative.
