Different fuel filters were sold over the years by Chrysler as service replacements, all under the one part number 2084 467. There have been all-plastic ones, all-metal ones, and plastic ones with a metal end cap. There have been numerous different styles of printing on the filters, too. FWIW, the factory parts catalogue shows an all-metal fuel filter, though this is not necessarily indicative of what was installed on any given car at any given plant on any given date -- FPC pictures are widely re-used without alteration from year to year and certainly would not have been changed just because the fuel filters Chrysler bought this month were a different style than the ones they bought last month. Doing a search at
Atlas Chrysler's page for
fuel filter turns up
this result for '64-'66 A-bodies and
this result for 1960-'63 A-bodies. I'm sure these filters look excellent, but I am not convinced by this page that all '64-'66 factory filters were metal; I have owned 1965-production plastic filters that look like Atlas' "1960-'63" item, but with different printing including the Pentastar logo rather than the Forward Look. Also, 1960 cars did not have fuel filters from the factory; that feature wasn't added until 1961.
It is extremely unlikely that factory-installed fuel filters were changed when the car arrived at the dealership. Also scroll back to
post 1369 in this thread and take a look at that factory photo of a 273 engine, with its metal fuel filter clearly visible. Does that prove anything about this car from this plant on this build date? No, but it's a data point!
