22nd Fuel Pumps

Hi All,

I believe my fuel pump is on the way out, the glass bowl won’t stay consistently full. The car also is having some intermittent running issues still when restarted hot. It’s possibly the flex line collapsing, but I’m aiming to replace that and get the pump rebuilt anyway since I’m close to then-and-now and it’s relatively cheap insurance.

I’m spinning a bit with all the pumps and numbers in my research and hoping someone can set me straight. The car is a 49 2262-9 288ci deluxe 3spd no electro clutch. Im wondering 1. What is correct for the car 2. What will work on the car 3. What’s an outlier that I won’t need. I have a parts haul that came with all sorts of things mostly useful for a 22nd but a few things for other models or engines. Here’s the breakdown:

-on the car is a Carter M946S (rebuilt by then-and-now around 2018 and in use since)
-I have a “core” M2049S
-also a “NOS” Ampco 9116A which came in a box stating Packard 8cyl 48-50, but it looks very different than my carters with its little chrome hat.
-there was also a rebuild kit labeled for 48 PAC, number FPK104

I have the exact same model and year Packard as yours. Mine has a Carter WDO-644S. I have an extra one that might need a kit, but other than that, it's in excellent physical condition, for sale.

Thanks Todd, I think the 644s is the Carter carb. I will keep yours in mind though when I get my new engine in. I’ll need a carb in better shape than mine at that point.

Any NOS fuel pump is going to need a rebuild kit. Period. Full-stop. If the rubber isn't already dried out, then modern ethanol fuel will surely finish it off in short order.

Penny, as you're new-ish here? at the risk of eyerolls from regulars, i will again post one of the longtime vendors i've known for decades who has correct fuel pump for your car with fresh diaphragm: Jeff Adkins, Moose Motors, Penngrove (Petaluma) CA (707) 792-9985, packardguy54@sbcglobal.net Jeff is reasonable, prompt shipping, a lifelong Packard wrench selling mechanical and electrical parts for 1935-56 Packards, as well as drum brake parts for everything from Auburn to Zephyr. Please tell Jeff that a '47 Super Clipper in Walnut Creek referred you.

The other vendor I like is Mike Grimes at Max Merritt Packard Parts, Indiana, who will have most everything including trim and cosmetic items. (317) 736-6233 ext. 103, or cell (281) 793-3377 mike@packardparts.com Again, please tell this gentleman I sent you.
www.packardparts.com

There are of course many other longtime Packard vendors, and you can find them clicking "Directory" in the Main Menu to the left of this terrific site's homepage. But i like these two fellows who know every bolt and lock washer on your car.

If you do rebuild your fuel pump, here is a Youtube video that I followed when I rebuilt the fuel pump on my 53 earlier this year. There are some important assembly tips!

The fuel side of my pump was "okay", but the diaphragm for the vacuum side was toast.

Thanks all! I tried rebuilding the unit on my car when I first got it years ago and must have done something wrong because when Then and Now redid it, it worked. I think the carter units are what came on the car but I just can't find the number specifically in terms of the M2049S vs the M946S. The other unit, looks like an AC style, and absolutely I agree I wouldn't bolt it in as is without a rebuild. 53Cavalier interestingly that video is from the place that I use to rebuild my pumps! It's close to where I live so I can go in and drop it off and actually speak to people. They also do it on a quick turnaround. They say it's a 48 Packard pump on the video and it looks like the Ampco unit I have. They also have this similar video:youtube.com/watch?v=j6fgbsNyhbE where they rebuild an M946s about 5 years ago saying its off a 49 Packard... I wonder if it was mine? The timeline matches when I needed mine rebuilt and there aren't that many on the road here. That video and this post is what comes up on google when you search Carter M946S fuel pump. The manual doesn't seem to list the fuel pumps, just the carbs, though my copy is down in the car to doublecheck that.

From what I've been finding here and elsewhere, it seems either carter will likely work (maybe the AC too). So I'll probably have the 2049 rebuilt since it's out of the car already and so I don't have to go without a car for a week.

I have a 23 rd series with same engine. I bought a rebuilt fuel pump from Max Merritt last year. Car is running great now, no hesitation when accelerating.
