Dave,
Here is an article in the Knowledgebase that details the layout and function of the fuel tank system in the XLR (and Corvette).

Highly non-trivial job, Dave. It took my dealer a couple of days to do it (thank God the dealer I bought it from had to foot THAT bill.). If you don't have an extended warranty, get out your wallet. It's a bear.
BTW, it seems that we have the same fuel system as the 'Vette, so a Chevy dealer might do it for a little less. Just a thought.

As a former motorsports dealer, may I suggest you try anything else, before going after the pump/gauge issues. Like, for example, the Techron treatment mentioned in other threads on this site. Always try the cheapest and easiest stuff first, is my motto.
Thanks guys, Trying the GM product now. Will let you know how it works. Noticed some folk get upset on this site when one gives their opinion but it is funny.

Probably becacause must of your posts are *****ing about what a bad car the XLR is. Perhaps you bought a lemon and didn't get rid of it. If you have a problem and ask a question, must will help or steer you in the right direction. But when you constantly *****, your chances of getting help diminish significantly.
Send me info on your car, if you want to get rid of it. I will find someone who will enjoy it.
You have a first year XLR. First years of a new model often have more issues than later, even when it's not a Cadillac. I imagine the first year edition of your much beloved Corvette C7 will be generating similar commentary ten years from now. Doesn't mean it's a piece of trash.

Also, XLR's & C6's share a very high percentage of parts and problems.
