desoto1939 Posted January 20, 2011 Report Posted January 20, 2011 If you supply me with the model car or truck upto 1951 I can answer which mdel fuel pump was installed on you vehicle. remember some mopar used vacum wipers and other had electric. My 39 Desoto uses an AC 588 and this was used on most of the cars from 38 and up. Rich Hartung desoto1939@aol.com Quote
crusader Posted January 20, 2011 Author Report Posted January 20, 2011 thanks. i found one on ebay that looks identical to what i already have and it's on the way. it's listed for a 57-59 plymouth-dodge with the 230. i need the pump without the glass bowl and without the vacuum fittings to clear my crossmember. my car is a 57 dodge crusader with the 251. i know it's not a 46-54 mopar but it does have a flathead... this forum is an amazing wealth of information. i would have given up on this car if it didn't exist.

Andydodge Posted January 20, 2011 Report Posted January 20, 2011 As far as I am aware the pumps will "interchange", ie bolt on but there are differences in the pumps regarding whether one has the lines in the same spot, vacuum fittings,gas bowl etc, but they will bolt onto either block. Quote
Alshere59 Posted January 20, 2011 Report Posted January 20, 2011 So at the risk of a thread jack. Will an ebay fuel pump last with the alcohol in todays fuel? If so are they easy to rebuild and are kits available. I ask as I am thinking of going that direction for the vacuum assit on the wipers. Quote

New fuel pumps are available at any good auto parts store and rebuild kits with modern rubber can be bought for even less money. Quote
Jim Saraceno Posted January 21, 2011 Report Posted January 21, 2011 When I first bought my car I bought a NOS fuel pump on Ebay. Sure enough, it lasted about a month before the diaphragm started leaking. I then bought a new fuel pump from NAPA, the one with the glass bowl on the bottom. It bolted right on but wouldn't clear the splash pan. I then sent off to "Then and Now" antique auto parts and got a rebuild kit for my original pump. That has worked fine for 6 years now. Moral of the story... never buy old rubber. Quote
desoto1939 Posted January 21, 2011 Report Posted January 21, 2011 There are certain fule pumps that are no longer being produced for an example is the AC588 with the glass bowel. I have contacted Airtex and they no longer stock these models. Some people have even stated that NAPA no longer has them in stock. With htis in mind then it would be a good idea to purchase an old rebuilt unit for a backup but you will need to get it rebuilt with the new style diaphram that can handle the enthinol based fuel. We also should have a backup pump on hand and also might have an electric pump installed as the real backup incase of a failure to the mechanical. Rich Hartung Desoto1939@aol.com Quote
Alshere59 Posted January 21, 2011 Report Posted January 21, 2011 Thanks that is what I thought. Ebay may be good for a core but if you want piece of mind get it new or rebuild. Quote
