Fuel Filters: AC Delco GF481 vs GF626
Posted to Technical Discussion Forum on 9/30/1999 5 Replies

I am curious if anyone has noticed that some fuel filter applications take a GF481-91 C1500 5.7, and some call for a GF626- 93 C1500 5.7. They both look alike and fit. Has anyone found out what the actual differences are? Login to read more.
