HELP! What is the stock fuel pressure for a return-style truck?

I can't for the life of me find what the stock fuel pressure is for a return-style 99-04(?) truck.

Is it 58psi? I've seen anything from 50-58.

If it is anything less than 55-58 psi KOEO you might want to replace your pump and or FPR.
