Latest AC Delco PF63 Specs

I did several searches and can’t come up with a prior post regarding the latest specs for the PF63. I was under the impression that Delco discontinued the PF63E and the PF64 was the replacement. Even the Delco parts lookup for my 2017 GMC 5.3 shows the PF63 currently and no longer displays the PF64. Specifically, is the bypass setting at 22 psi for the PF63?
Any insight would be appreciated.

I’m tracking 22 psi bypass for current PF63. Main difference between PF63E and the current PF63 is the metal end caps on the PF63. The PF63E had fiber end caps.

Thanks.
Maybe I dreamt the PF64 being tagged as the replacement for the PF63E by Delco…

The PF64 is the same size as the PF48, with a 22 psi bypass vs 15 psi.
