Folks,
Airtex still makes new fuel pumps for 1957 Cadillac, execept for the 1957 75 series.

Anyone know what the difference is?

My parts book has only one pump for all 1957 models, except Broughams of course as they have an electric fuel pump in the fuel tank. Are you sure that it's not the 70 model? (Brougham)

John, where did you find the information? Airtex online catalog shows no fuel pumps for the -57???
Anyway, the pumps are apparently the same for 57 all, except the Brougham as Roger says,
but the filter has a return line for a/c cars - maybe Airtex pumps comes with the filter
and they assume that all 75's have a/c.?

Kurt,

Got the info out of my old Airtex catalog. Second if you check the number these pumps are still available. Friend just bought a new one from NAPA. I believe I found it a Auto Zone.

All the '57's used the same pump.  Like just about everything else on these cars, it is a one-year-only unit.
