Re: {Chrysler 300} fuel pump question/recommendation

I believe I have solved the mystery of fuel pump numbers.

I came up with this list of manufacturers and model numbers that cross reference to the Carter M3672:

NAPA Fuel Pumps	B0002P
Precision Fuel	M16077
Purolator	267
Spectra Premium	SP1064MP
TruGrade	A13132191TG

The O'Reilly M16077 is made by Precision Fuel as shown above.

The Autozone A1604MP is the 'A'utozone version of the SP1064MP from Spectra Premium, which is also the same as the TruGrade A13132191, which was also printed on the Autozone box label.

Seems sort of like the old VCR days. If you went into a big box or audio/video store, you'd see multiple brands/model numbers of VCRs, but if you looked closely, you'd notice the on/off, play/stop/rewind/pause buttons were all in the same place, just different colors or logos.

The full details for those looking for too much information are here:

1-800-Radiator	2960308
AIRTEX	6972, 267
Airtex Fuel Pumps	267
CARQUEST Fuel Pumps	267
Carquest Premium Fuel Pumps	2541138
Chrysler	2463 917, 2495 528, 4094882
DELPHI	MF0056
Dana Commercial Vehicle Service Parts	602-1074
Delphi Fuel Pumps	MF0056
Facet	267
GMB	520-8120
General Motors	6416085, 6441474

For those of you still playing fuel pump trivia at home, I have more info that just keeps getting weirder and weirder-

Upon closer inspection, I have the following to report:
As for the Autozone replacement pump that is currently on the G (that I'm not sure I trust)
I have the following info/numbers-
On the box, and my receipt, is model number A1064MP (Mechanical Pump).
Also on the box, is printed A13132191TG
Inside the box is a little ziplock bag containing an instruction sheet and two gaskets. On the outside of the ziplock bag is a stick on label that says M3672BD. Zoiks! the famous number M3672 some of you mentioned in the thread. it appears nowhere else.
On the web page, specs for minimum 2 psi and 20 gal/hr are listed.

On the O'Reilly pump I might switch to, the model M16077 is printed on the box and my receipt.
Stamped on the actual pump itself is M20116, followed by the number 25349.
No additional tags or numbers are on the documentation/installation papers in the box, so no reference to M3672BD anywhere. Specs listed on their web page say 4-5.5 psi and 30 gal/hr.

The pump I took off the G has a sort of sunburst circular pattern similar to what can be found on alternators to be used with a magic decoder ring that I don't have. In the center of the sunburst is the number 84. On the opposite side from this stamping is another stamping that says Made in USA.

Just for kicks, I looked on the box that my replacement pump for my Hurst came in, and it says A1142MP (Mechanical Pump) on the box and receipt, as well as A13132255TG. There are no specs for pressure or flow rate on the web page for this pump. It only states that it fits 1970 Chrysler 300 equipped with U code 440 engine. It's been on the car for a while now with no issues.
On the actual pump I took off of the Hurst, is a stamping that says 484541C.

Feel free to make any of this make any sense. I couldn't find any info on M20116 on the internet, and when I searched on the 484541C stamping on fuel pump I took off the Hurst, it returned results referencing International Harvester equipment. Pretty funny.

Personally, I wouldn’t trust any modern fuel pump from a chain auto parts store. Cheaply made foreign junk. On my 55 Desoto (possibly the same as C300?), I located a used correct factory fuel pump. Carter 2241S. Then I rebuilt it with a kit from Then and Now. Once on the car, it started up and no problems since.

One of the issues with modern pumps is that they put out too much pressure, which can result in issues with the needle and seat. Also flooding of the carb. John, you may want to pressure test your Autozone pump. Should not be more than 5-7 lbs.

Subject: Re: {Chrysler 300} fuel pump question/recommendation

I picked up one of these from the local Autozone:
https://www.autozone.com/p/trugrade-mechanical-fuel-pump-a1064mp/348640?
After installation, I drove about 45 miles to a car event with no issues/leaks/smells. I stayed for about 2 hours, as it was getting hot outside, and the following happened-
I left the show and drove about 2 miles to the entrance ramp of the highway I was taking home, and my car got up to about 50 mph and would go no faster, started to stumble if I tried to give it more gas pedal, as if it was fuel starved. This lasted about 10 seconds, which felt like a lot longer, but then the situation cleared up and I drove home at about the 75 mph speed limit. When I got off the highway onto secondary roads, the car stalled at the first stop sign I came to. Car started right back up, then went the rest of the way with no issues. I had never experienced anything like vapor lock or fuel starvation, etc. with the old pump, but it was dripping/leaking fuel, which is why I changed it.
The new pump bolted right on, had the correct fitting for my gas line, and both inlet and outlet were in the same positions as the one I took off the car, but I don't trust it at this point, and will be returning it for a different unit and hope that all is well after that.
