NOTE: If you have a glass bowl or older rebuildable type, and you wish to keep it on your Imperial, you may need to send it to a rebuilder or search for a NOS unit thru a specialty vendor.
NOTE: All 413-400-440 Engines may physically use the same fuel pump as the mounting dimensions are the sameand the pumps will fit. The location and size of the plumbing fittings MAY NOT be the same, otherwise they will work satisfactorily.
Here are the Carter TQ number that I was able to lift from Govier's interchange book. The numbers go from 1971 to 1974. The letters listed under Models refer to carline (First letter of the VIN).

Many thanks to Brad Hogg for supplying us with this information.
Due to the fact that Chrysler no longer
produces many of these parts and that Chrysler part numbers are quite often
superseded or not in the Chrysler parts system any longer, aftermarket
numbers are used. If enough current and correct Chrysler numbers are
available, they can be added for what is still available from Chrysler.
I have arbitrarily chosen NAPA parts for the aftermarket, simply because of
the availability of NAPA outlets and the fact that I have previously worked
in their parts system. This IS NOT an expressed or implied advertisement or
endorsement to use these products. MOST PARTS OUTLETS CAN INTERCHANGE THESE
NUMBERS IF YOU DO NOT HAVE A LOCAL NAPA OR PREFER NOT TO PURCHASE FROM THEM.
IMPORTANT: ALL THESE REFERENCES HAVE BEEN ONLY SEARCHED FOR IMPERIAL OR NYB
AS APPLICABLE. WHEN RESEARCHING THESE PART NUMBERS I SEARCHED FOR IMPERIAL,
MODEL YEAR, ENGINE SIZE AND ANY OTHER NECESSARY DATA PERTINENT FOR THAT
PARTICULAR PART.
FOR EACH GROUP OF PARTS THE SOURCE AND BRAND WILL BE LISTED, AS WELL AS
ANY IMPORTANCE OF THE PART NUMBERS USED. IN THE CASE OF REBUILDABLE PARTS OR
PARTS NOT EXPRESSLY NAPA- NOTES WILL INDICATE THE USE OF SUCH NUMBERS AND
SOURCE.
Now when some uninterested, uncaring and uninformed counterman says "
they didn't make that in that year......" or " its not
listed...." you will have the upper-hand.
Many times a part is not available because the rebuilder has no "cores" from which to remanufacture a part from. It is usually possible and sometimes cheaper to send your part in - if you can be without the vehicle for the time required. Most of these parts are rebuilt by major suppliers to parts stores, regardless of the individual outlet. ( It is not uncommon for competing retail stores to be supplied by the same rebuilder) Some parts require the services of smaller specialized rebuilders, especially for vintage or very rare applications...
The following is a non inclusive list of many of the parts that can be
easily rebuilt today:
Alternators, Generators, Starters, Water Pumps, Power Brake Boosters,
Carburetors, Distributors, Brake Shoes, Master and Wheel Cylinders, Brake
Calipers, Air Conditioning Compressors, Power Window Motors, Convertible Top
Motors and Cylinders, Power Steering Pumps and Gearboxes, Wiper Motors,
Motor and Trans Mounts., Fuel Pumps, Harmonic Balancers, Driveline Supports,
Clutches and of course - Engines and Transmissions.
So if all else has failed, find a local or larger scale rebuilder either on
your own or thru a parts store. DON'T SCRAP THE PART - if you have patience
you can usually find someone to help.
