I had already seen the video but he makes no mention as to whether the pump is more reliable. he just states stronger to handle more pressure. The CP4 fails due to lack of lubricity if this wasn't changed the new ones will fail as well. GM went to DENSO to avoid this issue

What changes were made to the CP4 for 2020?
