Uhhhhhhh you better have them check the labor time guide again. That pump in the LB7could be done at least three times for the 13-14 hours you were quoted. I realize it was bid at a FLATRATE but there has to be a limit. Did they pull the numbers out of their "BOTTOM?" GM warranty flat rate time pays 4.0 hours plus up to .3 hours to diagnose ::snicker:: Keep in mind, theses are what gm will pay us to repair the vehicle under warranty. 9 out of 10 times it isn't enough. That's why there are Mitchell/ Haines/ Alldata flat rate guides to go by when the vehicle is out of warranty. The times are alot more realistic. Good luck with your pump.
