AC Delco oil filter number ????

[MDJR]

Can anyone tell me what is the correct filter for a 2002 Chevy Tahoe L59 Z vin 5.3L flex motor? Pep boys lists PF61, but looking in the manual it says PF59, an on RockAuto it's PF46, which is shorter... from what I understand the 46 is the shorter version of the 59 and the 61 has no back flow valve in it? Does anyone know or can you tell me what you are using please.

Thanks
