Primary fuel-filter head assembly identified by Isuzu number 8-98312915-1 and compact search alias 8983129151. Exact-number equipment catalogs identify it as a fuel-filter assembly or primary fuel-filter head with hand pump for Isuzu 4HK1/4HK1X applications. A dated Sumitomo 4HK1 parts catalog lists 8-98239466-2 as the earlier assembly used before 8-98312915-1, so the older number is retained as a catalog-supersession reference rather than an unrestricted direct interchange. The retained owned image shows the matching cast filter head, primer connection, port layout and mounting flange. Confirm the full number, port positions, hand-pump arrangement, mounting pattern and engine serial before ordering.
