fuel pump question

[scottyv47]

well i guess my fuel pump went, i was reading all the older treads about part numbers, the m847 m547 and m2090 numbers from napa are no good, they say all there numbers start with E now, autozone, advanced and all other numbers are no good, and say they cant get one, now there are a few on ebay, and from what i read on your old threads there all the same, except glass bowl or metal, but looking at the pics on ebay some have the cam arm sticking straight out, like i assume ours are, but some have them shorter and bent down, and some have them shorter and bent up, does anyone know where i can get a new one at a decent price, i dont care glass or not, i just want to get to our cruise in , sorry don if i should have added this to my old thread

For anyone to help we all need to know what year of truck/car that you have and also the model. This is needed so we can look up in our cross reference books.

Also I would suggest that you purchase an electric fuel pump and install this as close to the fuel tank as you can get it. The electric pump will pump gas through the non functioning pump when it fails. So if you are onthe road or on a trip and the mechanical fials on you then just switch on the electric and the car will still run. They cost about $55 on the ebay also it helps when the car has sat for awhile and it can be used to prime the carb so you do not have to grind the engine and wait for the fule to be pumped from the tank all the way upto the carb.

If you take out your old pump and can get a number off this pump then you can take it to a NAPA and then can cross ref also then you will know the correct arm location and style.

On my 48 Dodge, the fuel pump stopped working.

I took the pump off, gave it a good cleaning, and installed.

It has worked great since. It was just full of junk.

For what it is worth, NAPA Online still shows the M847 fuel pump: http://www.napaonline.com/Catalog/Result.aspx?Ntt%3dM847%26Ntk%3dKeyword%26Nty%3d1%26Dn%3d0%26D%3dM847%26Dk%3d1%26Dp%3d3%26N%3d0

Original Chrysler part number for the '39 to '48 Plymouth fuel pump is 683056 which might help on other cross references.

Personally, I'd order the repair kit from Antique Auto Parts Cellar (a.k.a. Then and Now Automotive) and rebuild the old one.

Todd: If my memory is correct then this should cross ref to an AC 588 fuel pump that would have the glass bowel. This is what is used on my 39 Desoto and was used from 38 throuth the 40-50's. The 588 does not have the connection for the vacuum line for the wipers.

i went to napa and tried every part number given in the old post, including the ac588 the m847, the m547, and all the rest, i also tried rock auto, advance auto and autozone, no one has it anymore, they all say the numbers are good numbers, but from there old system, and they use a new system now, the car is a 51 plymouth belvedere 218, and unfortunatly it doesn't have the good style with the glass bowl or i would rebuild it

[scottyv47]

i also tried jegs and summit

[Plymouthy Adams]

that is bunk..regardless of the sytem used...the part nuymb ers are constant..and cross referecne exist between every system/company/supplier/retailer Ihave ever done business with...get an electric and tell these parts guys to pack sand...!

yeh, thats what i'm thinking too

[desoto1939]

I just did a search on 588 fuel pumps and found several AC 588 pumps These are not cheap since they are not produced but they can be had for a higher price. I suggest that when going to flea markets still look for them and buy a couple just for the bodies and parts and then have them rebuilt.

wow with my new carb, electronic ignition and an electric fuel pump it will almost be like its a car from the 20th century, ha ha

[Plymouthy Adams]

some industries only rebuild a certain product for a short period and thus flood the market at one time..with the large amount of these pumps failing...the supplies are probably exhausted and who knows when the next run will be produced..who knows if the new diaphjrams are available in bulk to the rebuilder for new fuel requirements...I know for certain this is how some parts are done as I was on the waiting list and was told the exact day prodcution would start anew..they only produced x number every two years..I went with another product...

the antique cellar (think this is right, I am an electric fuel pump guy myself) may be your best bet for a diaphram and self build the unity..

Don't give up untill you try:

Roberts Motor Parts: (978) 363-5407

Andy Bernbaum Auto Parts: (617) 244-1118

Vintage Power Wagons: (641) 472-4665

Go to the Imperial Website there are more listings

Everyone on Ebay thinks they should get double what these guys charge.

yeh i saw them, but like i said, even though there same part number, they show different cam arm pictures, some straight, some bend down and some bend up, i want to make sure i get the one i need, thats why i want from parts dealer, not ebay, because if it is wrong, i know i can return it, i'm on a very, very tight budget, and cant afford having wrong parts laying around my house that i cant send back

[Tom Skinner]

Scotty,

I'm sure if you call the guys I listed with your engine size etc. and question them as to which way the arm comes off the back of the pump (straight, down, up) they will give you the correct answer. They are there to help make a satisfied customer - not to rip you off. Gary at Roberts, Chris at Bernbaums, and not knowing any one person at Vintage Power Wagons, I can say these guys know what they are talking about/selling and want to help out. After all they need return/our business, how many people are going to be asking them for parts for our cars (a finite number) need more parts down the road (no pun intended). Therefore I would pick one to trust and ask questions and go from there. Besides if Ol Andy were still there - even he would be helpful even if a little gruff (he was known for that by some people)over the phone. Its important to connect with a supplier you feel conforatable with, you will probably need more stuff/parts again.

Here is the pictures that you need to answer the question on the arm.

According to my AEA carb and Fuel pump catalog for 46-54 they use the AC 588 pump and uses the rocker arm RA-7.

I have a picture of two 588 fuel pumps that I currently have in my stock. Both ar NOS. If you look at the picture the arms both come straight out from the body and are in plane with the flat edge at the top. The distance from the flange to the lower point of the angle for the cam is 1 1/2 inches the length from the flange to the other end of the angle is 1 7/8 from the flange.

This is the stock pump for your car and I hope this anseres your question.

Call me if you want to talk 484-431-8157 cell. I live near Philadelphia PA

My truck quit running on Sunday and I suspect a fuel pump problem so I went to my local NAPA and they said I needed a M2090, and they had the part in stock.

I think I will order a rebuild kit good for ethanol fuel and fix up my old one.

yeh for some reason they still carry the one for the trucks which is different, it has the bend down cam arm on it

[desoto1939]

Here is another idea. Purchase the current Hemmings Motor News. Then do a search in the magazine and look for Fuel Pump rebuilders. Look for Art Gould up in NY state. Here is a major fule pump rebuilder and should have some or as I showed you the pictures of two 588 FP's the arm is straight out on these units and this is the correct pump for your vehicle.

You are going to have to spend some money to get these pumps but that is the only option left or get a used 588 pump at a swap meet and then rebuild it yourself.

The external part of the truck pump is a different shape but as long as it doesn't hit anything it will work just fine. The cam lobe is just round it doesn't care what part of the rotation pushes the fuel pump arm.

Tim,

What elec pump do you use that don't bus your ears off?

i actualy got another one last week, theres a guy right down the road from me that has and restores old cars, doesn't have any mopars but he has garages and school busses full of parts and he had the exact pump as mine, never new the guy was there till last week, and he's honestly less than a mile from me, he has the biggest collection of old signs, licence plates, and car parts that i've ever seen in my life, just thousands and thousand of them, he just retired, and his wife is retiring next year, then he plans on opening a little store and selling all his car stuff
