OEM Fuel pump

[Gunner41]

Good evening all.

I replaced my fuel pump about 6 weeks ago in my 1997 3500 CC/Dually with a 454 or some call it A 7.4. I could not afford a OEM from the stealership and had to go with just replacing the pump at the time and not the whole module. I will use OEM as much as I can but for some reason I just have to bite my lip every time I go in there.
I am looking for an OEM in-tank fuel pump (the whole module) part number. I keep coming up with conflicting numbers and I absolutely hate removing my bed. Yes I have got pretty good at it but I don't like it.

Thanks all
