ozzie1949 Posted May 9, 2011 Report Posted May 9, 2011 What years/models will typically interchange with each other? Does anyone know of a store then can typically get them in stock. If what is a good place to get a kit? 1949 desoto. Quote
Powerhouse Posted May 9, 2011 Report Posted May 9, 2011 sorry, not sure. But I got one once for a 218 and it looked ok, except for the arm that contacted the cam shaft..it was too long. Make sure you have the measurements when ordering. Quote
Andydodge Posted May 9, 2011 Report Posted May 9, 2011 I always have thought that all the mopar 6 fuel pumps will interchange with each other, whether from a 23 or 25 inch engine, they all have the same mounting boss and the cam is in the same place on all so the arms would have been the same length............but happy to be shown am wrong.........the differences I thought between the pumps related to the inlet/outlet and whether some had the glass bowl etc, but they will still bolt up.........andyd Quote

One pump fits short and long block engines. Quote
Niel Hoback Posted May 9, 2011 Report Posted May 9, 2011 Some where I have stashed a fuel pump from a 218 that has an "L" shaped arm that rides on the side of the cam instead of the bottom. It is my understanding that all fuel pumps fit all engines. You may have to bend the lines on some to hook them up, but they will all pump. Quote
desoto1939 Posted May 10, 2011 Report Posted May 10, 2011 According to one of my catalogs that covers carb and fuel pumps the 1949 Desoto uses the cater fuel pump M639SB and repair kit M20,007B I would also think that an AC 588 would work in your car. Rich hartung Desoto1939@aol.com Quote
ozzie1949 Posted May 10, 2011 Author Report Posted May 10, 2011 The carter I took off had a straight arm. I found a new one but had glass bowl and had a hooked arm. Same mounting holes. If I did some work with the lines would the pump work? It was for a 1949 dodge truck. Quote
Andydodge Posted May 10, 2011 Report Posted May 10, 2011 Sounds like there are different shaped arms, ie, short and long but I think that would have been because of the amount of space beside the engine and to allow the pump to be removed.......the cam doesn't care whether the arm rubs it on its side, bottom or wherever...........lol.......andyd Quote
Jim Saraceno Posted May 10, 2011 Report Posted May 10, 2011 The only reason some pumps won't fit on some cars has to do with clearance. For instance, the standard fuel pump with the bowl on the bottom won't fit my '35 because it won't clear the splash pan, however it will bolt to the block just fine. I would think you could get a new fuel pump at NAPA or a rebuild kit at Antique Auto Parts Cellar ... http://www.maritimedragracing.com/then_and_now_automotive.htm Quote
ozzie1949 Posted May 12, 2011 Author Report Posted May 12, 2011 If I go with an electric fuel pump, does anyone know of a company that will run one with a positive ground? Quote
Niel Hoback Posted May 12, 2011 Report Posted May 12, 2011 Airtex E8011 6 Volt, you can wire either way Pos grnd or neg grnd. Quote
ozzie1949 Posted May 12, 2011 Author Report Posted May 12, 2011 Thats the one I have how do I switch polarities? Quote
Niel Hoback Posted May 12, 2011 Report Posted May 12, 2011 Connect the black wire to the 6 volt power and ground the other wire. Quote
JeffLeav Posted May 16, 2011 Report Posted May 16, 2011 I am trying to determine the correct fuel pump for my 1948 B1B so I can rebuild it for today's ethanol fuel. Please see attached photos. The 'A' photo is off the truck and was found under the seat when I bought the vehicle and includes the glass fuel bowl. The 'B' photo came with the truck also and is currently mounted on the engine. Does anyone know which fuel pump is closest to original equipment? Please let me know if more information is needed. 1948 B1B Fuel Pump A.pdf 1948 B1B Fuel Pump B.pdf Quote

I would think and this is my opinion that the pump with the glass bowel would be the pump that was used onthe truck. The pump without the glass bowel can also be used. The bowel helps you know when there is sediment inthe line and to clean out the bowel. If the pump doesnot have the glass bowel then definately put an inline fuel filter on the truck. I own a 39 Desoto and my AC588 pump has the glass bowel. I would suggest that you post this onthe truck side so that the truck guys can better anwser your question. For AACA juding they are not going to be looking that close at the engine and will not get down under the truck to verify if a glass bowel or not. Rich Hartung Desoto1939@aol.com Quote
Merle Coggins Posted May 16, 2011 Report Posted May 16, 2011 This is the fuel pump that WAS on my truck ('50 B-2-C). It is an AC knock off purchased from Andy Bernbaum. It was installed when I built the engine, but I later rebuilt the "original" pump with a kit from Antique Auto Parts Cellar. http://www.maritimedragracing.com/antique_auto_parts_cellar.htm The rebuilt pump lived in a box under the seat until the "new" pump failed, leaving me temporarily stranded at a major intersection. (notice the pivot pin that walked out, next to my thumb) With help from a good sameritan I was towed into a nearby parking lot where I swapped in the rebuilt pump and was on my way. The "rebuilt" pump is still working just fine and I've since rebuilt the "new" pump with another kit from Antique Auto Parts Cellar. I had trouble identifying this "new" pump as it didn't have very good markings but when I sent some pictures to AAPC they identified it right away and told me which kit to buy. They're good folks to deal with. I don't expect any problems, but this pump will now live under the seat ready and waiting to someday pump fuel again. "New pump next to "original" pump. I had to re-index the top cover of the "new" one to match the "original" one. Quote
JeffLeav Posted May 17, 2011 Report Posted May 17, 2011 Many thanks, Rich & Merle, for the helpful words. I plan next to visit my local NAPA (just because they are close by and will play 'show & tell' with my fuel pump and will accept returns if the parts do not fit). Hopefully, NAPA will have a rebuild kit for the glass bowl version of my spare fuel pump. Rich: I was not clear about your suggestion to post my inquiry on the 'truck side' because I thought that is what I was doing when I made a thread search for 'fuel pump' and found this thread and replied. Please help me understand how to know which 'side' I am on as I don't mean to abuse site protocol. Also, when I logged in today and clicked on 'New Posts', this thread did not show up until I searched for 'fuel pump' again. Sorry to be so illiterate about forums, research on the web is not quite like the old days when you went to the library and checked out the Chilton's manual....actually, forums are soooo much better! Thanks again, guys, this is a great site, Jeff Quote
Merle Coggins Posted May 17, 2011 Report Posted May 17, 2011 Jeff, You didn't really do anything wrong except for tagging on to someone elses thread. But there's no punishment for that as it happens all of the time, and sometimes leads the thread off into new directions alltogether. Anyway... the low down... At the top of this page you see links to "www.P15-D24.com", "Welcome to the forums of P15-D24.com, Pilot-House.com and DEPTCA", and etc. If you click on the "www.P15-D24.com" link it will take you to the home page of this site. There you will see a list of different forums that are all somewhat interlinked. The P15-D24 forum is the "car side" and is where the guys with Plymouth, Dodge, Chrysler, and DeSoto cars hang out. The Pilot-House forum is considered the "truck side" where us Dodge and Fargo truck guys hang out. The DEPTCA forum is a somewhat redundant truck forum but is also a place to seperate out our club announcements and such. There are other forums listed as well, such as the Technical Archives which has several threads related to technical issues that are shared by "both sides". This thread just happens to be on the P15-D24 forum, or "car side". So, it cames back to which forum to post your questions. Many of the "truck guys" don't venture away from the Pilot-House or DEPTCA forums and many of the "car guys" don't venture away from the P15-D24 forum. And then there are many guys, like me, that don't honor the "border" and play on "both sides". So if you have a question that relates specifically to your truck you may get better feedback from the "truck guys" on the Pilot-House forum. Sometimes I'll post a thread on both forums if it is a topic common to "both sides". This way it'll reach more members. Many of the mechanical systems are common between the trucks and cars of that era. Merle Quote
JeffLeav Posted May 18, 2011 Report Posted May 18, 2011 Merle, Excellent explanation and now I know how and when to stay on my side of the fence... the truck side. Thank you for your patience. May I ask another question? What does P15-D24 mean (I'm probably violating the virginity of the thread with this question)? Grateful for the knowledge, Jeff Quote
Young Ed Posted May 18, 2011 Report Posted May 18, 2011 P15 is the engineering/model code for 46-48 plymouths and d24 for 46-48 dodges. Sorta like your truck is a b1 b2 b3 etc Quote
JeffLeav Posted May 20, 2011 Report Posted May 20, 2011 Today, I ordered a AC fuel pump repair kit part #FPK100 for $44 including shipping from Harold 'Hal' Houghton at http://www.classicpreservation.com/index.html. More to follow after the rebuild. Hal offered to ship me the kit no charge; payment to follow a successful installation. I do not know if this is a reasonable price but it seemed in line, especially since NAPA did not list a repair kit after taking the fuel pump to the counter for 'show & tell'. Jeff Quote
