I have a 100k on it now, not sure if it has ever been upgraded or not. According to the Carfax the car has had a few thingas done, just dont remember what they are.
You remember what sponsor it was that had the pump, and might regret asking this but what does it take to change out the pump.

Drop the fuel tank, pull fuel level assembly, swap pumps, reinstall. If you go that route, I would suggest the racetronix hot wire kit as well.

Yup, and FYI, only a walbro has ever left me stranded, the stocker never gave me a single issue. I went with the "stocker is obviously bad news, replace and win" thought process... ah well.
