    Hi Everyone

    I have the original date coded fuel pump for my car.

    Does anyone know whether these can be rebuilt? From time to time I see other button top fuel pumps (non hipo) being advertised as "rebuilt".

    Thanks

    Rohan

    Hi Rohan,
    This issue has been disussed on the HiPo Ekschange Forum for
    years and we still haven't come up with a rebuilder that can
    do the crimped type of HiPo fuelpumps, 3939 for 65 and 4201
    for 66 models. The ones rebuilt by Ford that you can find for
    sale now and then are most likely done years ago.
    Sorry.

    Thanks for that - I wondered why some were being advertised as being "rebuilt".

    Because (likely) these are older stock, back when shops were rebuilding them. Often they either recrimped the lower body and thimble (sometimes pretty ugly) or in some cases a separate band was (not original design) was placed over the point where the lower and upper bodies came together

    Yes, I have a rebuilt 65 fuel pump with CARTER on the side
    instead of CARbureTER and it's marked 3909 instead of 3939 and has
    a NOS beautifully painted fuel bowl. It has the hipo spring
    under the arm but doesn't have the spring that goes up into
    the button. Obviously the rebuilder used another type of internals
    than the originals were equipped with as the spring is missing.

    With all the great gear and access to parts that you have in the US I'm surprised no one hasnt invesnted some tooling.
    I'll hang onto it and hope!

    It's most likely about investment, volume, parts etc.
    If the latter is the main reason, I don't think we have much hope
    of getting somebody to start a repair business.
    Fortunately, I found a NOS in the box 3939 some 6 years ago for
    my 65 Shelby. Unfortunately it's dated one month too late for my car
    but you can't get everything, I guess. Paid $500 for it at that time
    which almost cost me a divorse but when looking back, it was cheap.
    Had a NOS 3911 in it earlier that I traded for a used 4201.

    This is an update on crimped fuel pump rebuilding. I am actively gathering pumps for my fifteenth run. I have done over 750 of these so far. The $220 price is the same but the return shipping in the lower 48 states is now $18.
