swffsu Posted March 30, 2017 Report Share Posted March 30, 2017 Hi everyone, I'm having an issue with my fuel pump on my 49 dodge we want to be. As you can see from the photo below had to order a new fuel pump however the only one that they're showing available for the 1949 dodge has a different peice that goes inside the engine. My old one is straight and this is bent at an angle. They are telling me this is the only fuel pump available. I just can't seem to get it to fit. Any ideas? Thanks in advance for your help.

desoto1939 Posted March 30, 2017 Report Share Posted March 30, 2017 The old one is an AC588 fuel pump and was used on the dodge engines that does not have the connection for the vacuum wiper motor. Do you have a separate line that connects to the vacuum line for the wiper. Rich Hartung Quote Link to comment Share on other sites More sharing options...
Los_Control Posted March 30, 2017 Report Share Posted March 30, 2017 looks upside down from mine. But the goal is the same. The lever rides on a cam lobe, as the cam turns it moves the lever back and forth to operate the pump. If you find some resistance as you tighten down the bolts to the pump, that would be normal. If you rotate the motor a 1/4 turn or so, you may get less or more resistance, but will always be some pressure on the arm as you tighten it down to the block. You are moving the lever on the pump as you tighten it. Quote Link to comment Share on other sites More sharing options...

But if it does not work, you can drive out the pin and swap levers and spring from the old to the new. Just make sure that you really stake the pin so that it does not travel out on the road.

MBF Posted April 3, 2017 Report Share Posted April 3, 2017 If you can't make the new one work, you may want to consider rebuilding your old one (there are numerous sources for parts if you want to do it yourself, or rebuilders in Hemmings or on their website hmn.com). I bought a brand new pump from NAPA this past summer, when I put it in it leaked like a sieve. I went to tighten the bolts holding the two halves together and they were all stripped. I ended up rebuilding my old one for about 1/3 of the price. The kit has the newer material in the diaphrams that better tolerates today's gas w ethanol, but I usually run non ethanol gas in my old stuff whenever I can. 1 Quote Link to comment Share on other sites More sharing options...
lugnut123 Posted April 4, 2017 Report Share Posted April 4, 2017 I installed a fuel pump on my daughters b-1-b last week. It looked like your new pump. not the old one. Quote Link to comment Share on other sites More sharing options...
lugnut123 Posted April 4, 2017 Report Share Posted April 4, 2017 Does your old pump look like some one put the cam follower lever in upside down. And it isn't because the two fuel pumps are upside down anyway. noel in nm Quote Link to comment Share on other sites More sharing options...
Oberstar Posted April 4, 2017 Report Share Posted April 4, 2017 (edited) One pictured on the left is for a 218/230 motor. The one on the right is for a 251. Which motor do you have, brother? Edited April 4, 2017 by Oberstar Quote Link to comment Share on other sites More sharing options...
lugnut123 Posted April 4, 2017 Report Share Posted April 4, 2017 I have a b-1-b that has a 217 23 inch block. The b1b's pump I replaced looks just like the pump on the left. I didn't realize we were looking at 2 differint motors. noel Quote Link to comment Share on other sites More sharing options...
