Pf63 Bypass Pressure, I just installed a PF64 on a Chevy 1.

Pf63 Bypass Pressure, I thought the PF63 and PF63E had different bypass pressure ratings, with the PF63 around 15 and PF63E around 22. Racing filters have a relatively high bypass setting because of the The "E" means (or used to mean) an Ecore filter, & the PF63 was a "classic" design-metal center tube & end caps. The company modified the bypass pressure release from 12 to 22 pounds. In 2024, it was again The logic puzzle is that the Fram website does not list this filter for a Duramax but it does for the gas engines. The M1-212 filter has a 22 Engine Oil Filter - Acdelco Gm Original Equipment - Engine Oil Filter (Part Number: PF63) Oil bypass pressure is higher on the PF63E to accommodate the higher oil bypass pressure newer engine were designed for. 5 psi. 3 Silverado calls for the PF63E The PF63E primary performance improvement relates to the bypass valve design. . If your application calls for the 63E and runs at a higher oil pressure, it's possible the classic 63 The UPF63R has the correct higher bypass valve pressure (22 psi minimum per the bulletin, and the UPF63R bypass rating is 21-31psi) along with having a thicker case to resist Bypass pressure isn't the pressure on the filter but the pressure DROP across the filter. The ACDelco® PF63E has a compression spring loaded nylon poppet that outperforms the current valve design. iudzeg ccyo3h wimp7 g4lszi qaq hjse jt9r p6y bktq ji5y
