      Re: AC fuel pump date code research data

      Old thread new question.

      I recently purchased this 4657 pump. I also read a lot of the post on this site about prefixes, date codes, etc. I type have a June 63 327/340SHP original motor with a crimped type replacement pump. From what I've read it is highly probable that any 4657 pump you purchase will not have matching component parts. It looks like there were no suffixes on the stamp 4657 part number for 63. This does not appear to be a re-stamped either. The bowl outlets are correctly clocked on this pump but the date stamping on the unused side hole appears to be 67 with 10 hash marks. It was also pointed out that it would be very difficult to see that bowl date markings.

      So from a "correct" standpoint it looks like the flange is OK, but the bowl is from a later year model. Everything else looks good including the screw types / plating, etc. Were replacement bowls manufactured for older model fuel pumps or is this just a case where a newer bowl was used for the rebuild? Should I be concerned about this combination?
