1965 Cast Iron Pump

. . . with straight threads for the sending unit.  Usually, you get people who try to screw pipe threads into the straight threads or vice-versa.  If it's flat on top(for a brass washer) it's straight threads.  The straight threads are for the old "all steel" sending unit, with the knurling on it.  The newer plastic sending units have tapered threads.

Last year was 1967 for this pump with 1968 going to the alloy block style. Maybe that's why I like my 1967 so much. That and it was the last year of the Panhead style tin dash. Oh my!
