WD Bulletin 14D-038

ACDelco Oil Filters PF48 (GM# 89017524) and the Durapack version, PF48F (GM# 19167894) are transitioning to a new design that offers improved performance. The new part numbers are: PF48E (GM# 19303975) and PF48F (GM# 19303974). This will be a rolling change and the old version will not be available once stock is depleted.

The PF48E primary performance improvement relates to the relief valve design. The PF48E has a compression spring loaded nylon poppet that outperforms the current valve design.
