what is the flow rate of stock fuel pump

I did a search but did not find the answer.

With an SC, most people install a 255 l/hr fuel pump, but what is the rating of the stock fuel pump? 1999 Camaro SS LS1 car

I'd been wondering the same thing until I picked up Jan '06 issue of High Performance Pontiac. They are upgrading the stock pump on an '04 LS1 GTO and they said it only flowed 140 lph. I'm sure our cars must be about the same.
