I have created a line diagram for the fuel pump, so hopefully, I have understood everything correctly.

Interesting carburetor as, going from probably faulty memory, I believe all mine had the choke facing outboard rather than on the engine-side. Also, the 1953 Clipper Deluxe had a 2-brl carburetor but this appears, at least in the photos, to be 4-brl.

As for Max Merritt's breakdown of the pumps, I'm not sure what they are talking about. There may have been a different AC Carter number for the Clipper pump (the number stamped into the mounting flange) but it still would have been essentially the same as the others in external appearance as the same 327 engine was used in the 300 and in the commercial vehicles (hearses, ambulances etc).

That said, be sure to use the insulator sleeves that go into the mounting holes along with the fiber washers that go under the bolts' flat steel washers.

I tried to sort out the pump numbers but is a can-o-worms. I got run out of the garage by the heat early so was passing time til munchies.
If you look in the parts list it gives the Packard number which you have to cross reference to manufacturers. Sometimes P used the same last digits as manufacturer but doesn't appear to be the case here. Probably did not use Carter but my guess. They were more a carb supplier back then.
Carter no longer makes/lists that pump 2049 and hasn't even showed Packard in their catalog since before 2017(last FP catalogue). That would indicate, I guess, NOS, reman, or repop. Things usually go bye-bye due to low numbers and a v-small segment like this is ripe for the axe. As buyer, you'd have to contact Max to find out where they got their info/where/how they supply. I checked my old Max catalog circa 2013 and it shows the same info, then as now,"Clipper only" 2049. It's not the first.
In my period catalogs I show only one AC9590 combo pump as all 52-54 Packard. Consistent with owner comments.
Kanter shows the group number only and has a core charge so probably rebuilts, so you'd have to call them.
The interchange also listed AC 9606 and 9920 for '52-54 Packard# 433255 combo. That usually just insures fitment. The AC 590 pump top side looks similar to the Carter 2049, not the other one pictured.
There weren't too many of the combo style pumps made so it should've been straight forward but there's a wrinkle in the period time warp. Since the car is located foreign country, who knows what it has/was delivered...
It'll be interesting to know if it fits as discussed. Some levers can be changed.

Yes, they were all AC in that era now that you mention it. I misspoke when I said Carter as only my 1956 Clipper has that type.

Thank you, gentlemen, for your contributions. I am a bit confused by all of this. I am planning to install the pump over the weekend and we will see how it goes. I am curious myself. I will keep you informed. Just to clarify, the pump is indeed a Carter with the label M2049S.

Hello, gentlemen. Everything got delayed, I waited a week for the fitting. During the wait, I at least made bronze inserts for the screw holes. The holes were too large. Today, I mounted the pump. Everything fits, seals properly, and the engine is running. Now I just need to adjust the carburetor. Thank you all for your help.

Is there perhaps a manual available for adjusting this carburetor?

I don't know what your climate and driving may be like but you may need to rethink the bronze bushings at some point.

The original and proper bushings are phenolic or fiber and those along with a fiber washer under the steel washer at the bolts sitting next to the pump are designed to reduce heat transfer. With the fiber washer a lockwasher would be ineffective so the original bolts were drilled so they could be wire locked. There was also a thick gasket between the pump and block. All that along with the heat shield were designed to reduce both conductive and radiant heat transfer to the pump.

Thank you very much for this technical note, I was not aware of that, I will have to reconsider it.

I don't remember if you mentioned which model car you have but here are the carbs and initial specs used or all models. If you would let us know which model or carb you have, we could probably help with a detail sheet. Most carbs have rebuild instructions on site either as individual Carter sheets or in a service counselor. If not on site it may be available in an aftermarket book.

Once you identify the carburetor you might also check the service index on the left menu and go to 51-4 models, fuel and exhaust category, to look thru bulletins and see if Packard issued any that might have changed the adjustment specs on your carb.
