hipo fuel pump

  • Which fuel pump would be correct for my 65 hipo with a April 65 build date. I know it is a carter pump, but is it crimped or screw together design?

    When looking in the 4th addition of Tony Gregory's hipo book, it shows a picture of a 65 motor on page 59. The middle picture shows a crimped fuel pump, but the picture above shows a screwed together but says it is a 64.5 engine. So which one would be correct?

    Thanks Tim

  • Also on page 49 of this book, it shows a picture of a 3939 but it is a screw together. The book contradicts itself, unless there was a cut off of when it changed from screw on and crimped and it was still called 3939. Any ideas on this?

  • Thanks for all your assistance. I actually have one of of each style, but the crimped one doesnt have the actual numbers on it, but then i have the screw together pump that has the 3939 s on it. So i am guessing this one is a phony??. Both were sold to me at separate times and businesses representing they were both correct.

    Is there an upload button for adding the pics of my parts here for all to look at?

    you have to upload your photos to a hosting site like photobucket.com

    once they are there you can post a link here.


  • Ok, it worked, This is the pictures you requested to view of the 3939 carters hipo fuel pump showing the date code is 5h7. This is the screw together one that i dont know if its a fake or not. Thanks everyone for your expertise on this matter. Tim

  • The stamps are very fresh...looks redone to me.

    The 3939S pump is the button top, crimp together style.

    ACMAN63 has a Cobra and early HiPo screw together type on eBay right now - 3732S

    eBay item #280716703410

    I have a similar Carter X pump - on my car in '79 when I got it - the origianl 3939S pump was long gone.
