Fuel Pump Swap?????

I have to replace a fuel pump for my 92 grand Prix.(3.1 multi with 4t60-E trans). I'm just trying to see is there a specific pump I need besides it being form a grand prix with the 3.1. Cause I have replaced a radiator for this same car and it had to be specific to the trans. $90 is too much for me and i would rather get a pick a part with low mileage but I want to make sure I only take down one tank. Hope I was clear enough.

it's the same fuel pump on all 3.1s. $90 is high for new. if you by one at the yard it should be no more than $40 if they pull it, less if you pull it
