Topic: Correct fuel pump for October. 64 289

[DKutz]

I am having leaking issues with my fuel pump.  I believe it's a aftermarket replacement.  Leaking from gasket area around screws.  Someone said diaphragm.  Anyway now replace or fix?  I think replace but,  what pump?  NPD has one for $50.  Rock auto has a carter for $20, they look the same.  Suggestions?

Ford Car Parts (75 ed) say a Carter pump marked 3911S which appears to be the common pump used on all (ex HP) 65 289 engines. If you ask, many auto parts stores will let you, or help you, look thru their stock.

Maybe this can help.. I aquired an early 65' block last summer that had the specific Carter fuel pump Jim is describing. This one is stamped with the 3911S and is the "button top" type (arrow depicts the button top). However , it does not have the diaphram style that is connecting the two halves with screws as your picture shows.. Take this example for what it is. Perhaps the true style for an early "A" code would be the type that uses the retaining screws that hold the diaprams in place, yet have the 3911S and a "button top"??

Thanks!  No I don't think t he one I have in now is correct. 

What is the line that is running from the top of the pump?  I have never seen that before...

That "screw together" style is what was used for early 289 v8's but the oct 64 time period is when the changeover to the "crimp together" style. Maybe others can give you a more definitive ruling on which style is most appropriate. The limited angle makes it difficult to determine if it is a assemblyline pump or not. Maybe if you can take a front and back side view of the upper half portion would help determine that . Hopefully others can help determine a more exact changeover. A assemblyline pump of the screw together style is relatively easy to rebuild and uses the same 35.00 rebuild kit available from large vendors for the later Carter screw together BB/SB "screw together pumps that don't have the integral fuel filter bottom half. You can send a buttontop  fuelpump in to have rebuilt but it cost about 250.00 to get it done.  If something that works is all your after then the after market alternative is the least expensive but it should still be the filter bottom half style.

that line fooled me too. look closely and you'll see that is actually behind the button.

ha thanks!

I am just going to pick up a rebuilt carter from a local parts place.  Probably won't be exact, but its will be closer than what I have, and will get my car back on the road...

I'm guessing the line you are referring to is the old gas line coming up on the back side of the fuel pump??

It sounds that the rebuild kit for your pump would be the way to go. Cheap and easy to rebuild, (so I've heard). Included is also a pic of the fuel pump on my June 64' Dearborn coupe. I knew that the screw assembled pumps were the first style but I was not 100% sure that the one I used is the EXACT style for my 64. It still works as it should in making the car run!!

yup thats what I have.  I will save it and if it is correct for my car I will rebuild it later, otherwise I will leave the new one in.

BTW I looked briefly for a rebuild kit but didn't see one...

[Hipo giddyup]

  I will say, i bought an NOS fuel pump at a Ford Carlisle show several years back. It looked great but only ran about 10 total hours before the diaphragm ruptured. I guess that's the chance you take with a 30+ year old part??

Here's a link from VCM. I guess you would have to make sure your pump is a Carter or this might not work. Thinking this would be dependent on the total number of screws, height of pump spring, etc....

I had my Carter crimp style pump from my July 65 car rebuilt by Fred Ballard. See the thread below

Fred usually does them in batches, so he can get the plating done in quantity.
They come back using updated rubber products that do not dissolve in today's gasoline. (the old rubber previously used in the 60's & 70's WILL NOT survive long in today's gas)

Just an update.  I replaced the pump yesterday with a carter style repo.  I saved the old pump, not sure if its someting someone will need.  The diaphram had not burst, just dried ouut enough to allow fuel to leak out the sides.  It only took an hour and she fired right up with no leaks!!

Thanks for everyones advice.
