Fuel Pump ID Help??

[Als 70 L78 Nova]

I don't want to make any mistakes so I am in hopes that someone on this site can ID this fuel pump and tell me the date and year that it was built for. I believe it came off a running 1969 Chevelle SS.
Thanks,
Al in Maine

I believe the date code is 319th day of 1972

[Als 70 L78 Nova]

Do you think it is original or a repop?

[Billohio]

probably real. I think I read the repops had a circle around ac. It did appear to be correct for a hi perf big block

[WILMASBOYL78]

The #727 is the hi-perf unit found on the L78 cars and others...the "72" is not part of the date.

From the info I had showed L is 1972

[Billohio]

More info. Prior to around 1971, fuel pumps used 2 letters at the start of the stampings. First was month, second was year. Around 71, they dropped the first letter and used the Julian day of year then was the letter for the year. 2 things show this is a 71 or after pump. The day and year codes

[WILMASBOYL78]

Bill...I seem to recall another post about the dates on these. Thanks for the update...I have several originals...will have to look at the stampings and report back.

Yes 319L, decodes to the 319 th day 1972.
