Fuel Pump

Does anyone have a picture of the fuel pump used on the 55 Packards? I have seen two on Ebay and both have looked different. There wasn't any on my car so I can't match anything to mine. Any help on this would be great.

P.S. The reason I ask is that I may have a crossrefference for this part that only cost $13.00 <img src="/ubbthreads/images/icons/smile.gif" alt="" />

there ARE 2 different type. One is an original and the other is a retro fit that Packard vendors sell. I will try to get u pics to nite.

SEND ME AN EMAIL TO REPLY TO PackardV8@Juno.com

In short, one pump has a long arm about 6" long, is FLAT on top and sets about perfect perpendicular to the mounting flange. The other type has a kind of knee bent arm. The only thing i can send a picof is the original factory type. If your x-ref is for a big block ford circa 1975 i'm not sure it will work since the lever seems to set rather hi.

I have found an AC delco part # 4299. An example of this pump can be seen on ebay if you do a search of completed auctions. "1955 packard fuel" The pic shows the bent arm. I have seen the one in the shop manual which shows the strait shaft. But if you look at them the bend cancels out the difference. I have tried mounting.... it appears to fit.

Take a look at the ebay one if you can.

The pump I have is not the delco on but another that has the same arm bend.

The one o e-bay is the same as the one I just pulled out of the parts stash that I picked up in Milwaukee back in May. Chris car needs a new one and I was afraid I would have to bite the big one to get it. But lo and behold after much tiresome searching I found this one. I posted the xref for the gasket on the xref thread, but just in case you missed it, a gasket from a slant-6 mopar is a dead on match.

Well I think I may be getting closer to an answer to this one. I have seen a pump which should normally go to a 54-56 Dodge truck with a 260 V8. The arm looks like it will match the AC 4299 pump. It is at autozone for about 31.00.

I will keep all posted to the findings.

Regarding the mounting surface - that is almost immaterial as most fuel pumps from that era look about the same. How the arm contacts the eccentric and how much travel the eccentric causes in the arm are the two most pertinent questions. If not enough travel then you will not get adequate fuel. If too much, you will ruin the pump or eccentric or cam (eccentric being bolted to cam), or timing cover casting. Or all of the above. There are definite reasons that different fuel pumps are made.

I think I am being misunderstood here. I understand that they make different pumps for different applications. <img src="/ubbthreads/images/icons/crazy.gif" alt="" /> At the same time I don't think they need to be $85.00. There is not reason for that. In addion I don't have a core to send in. <img src="/ubbthreads/images/icons/frown.gif" alt="" /> Furthermore the mounting surface IS the same on almost all of them so if I can find one that has the same arm I will be in business with this thing and all of you will have a cheap alternative to add to the X-ref. That is all. If you don't know if there is one then don't worry about it. I don't intend on ruining a pump or eccentric on my cam.

Not a bad point! I have inquired locally about a fuel pump from some people parting out packards around here. One said that they didn't want to take it off of the car? <img src="/ubbthreads/images/icons/confused.gif" alt="" /> Either way I think I will try several things here. I just thought that if I could find one ready to go at the local store then.... well Cool! I have no problem with rebuilding a pump.

thats why i want a broken timing cover so i can cut it up, mount it on my spare engine (readily accessable at least for this operation) and check the fuel pump arm positioning and travel to the eccentric for various pumps i have laying around that look like they mite work.

If someone can look; Please do a search on ebay for dodge fuel pump. There is one currently for sale which states it is for a 54-56 dodge truck. The arm looks to be almost identical to the ac4299 pump replacement. I know that my local AutoZone has this in stock. I would love to have a second opinion.

yep, that eBay pump has what looks to be the same arm as the REPLACEMENT pump.

Here's the catch, we r not sure that the replacement (bent type arm) will contact the eccentric at the same point as the factory original. ISSUE: lubrication. The eccentric is lubed by a jet of oil DIRECTLY at the 6:00 o'clock position. If the replacement pumps arm contacts at say 8 o'clock then does that mean the possibility of premature wear to the eccentric???

I would think that would be the case with any pump that has an angled contact point. With that thing spinning around the oil probably will get splashed all about in that area regardless of where the contact point is. One way to check would be to put it on and run the car. Then take it off and look at the arm. If it appears oiled and there are no shavings.. well.

Perhaps I missed it in the string. but the Carter Pump # is M2198S and the BIG Carter book I have sgows the AC 4299 as equivalent. I have the Carter M2198S on my 55s and a spare of the same.

Nothing was missed... I had not stated the Carter # anywhere.... Again if the "right" pump were available for a cheap enough price I would have it on by now. Pump mounting is similar if not identical. The arm is the issue. The Carter pump I believe has the straight arm while the AC has a bent one. The bent one seems easier to find a X-ref for. I have not picked it up yet but I think the Dodge 1954-56 pump for the 260 V-8 is the dig for this one. I will keep everyone posted as to how it works out.

OK, for information:

Dodge, V-8

1953-55 Dodge Single Pump M2348S

1956 Dodge Single Pump M2414S\

I did not look up what might have been different between 1955 and 1956.

The pump I am refferencing is for the dodge truck with the 260 V8. According to Autozone they have this for $31.99. From the pics of the same pump I had seen on Ebay. The arm seems to be identical to the replacement AC pump. If anyone finds more info on this fire away!

My Carter book shows that same M2348S fuel pump for 1954-56 1/2 and 2/1/2 ton V8 trucks. The repair kit is listed as M20033. This is a Barter book from 1960, but perhaps you can cross reference to a NAPA or CarQuest Number.
