    Hi Hambers,

    does anybody know what thread is on the 1928 Model A Ford fuel filler neck?

    thank you
  2. '28 Ford didn't have a filler neck, just a bung on the top of the tank that a gas cap screwed to. Unless you are thinking of something that works with the tank relocated.

    henry made lots of '28-'29s,
    the threads were sometimes rolled into the steel or brass not machined, he may have used his own thread...

    @p&b:sure i mean that bung ;)
    @sloppy j: ok thank you
    i wanted to use those as exhaust cut outs. As it seems those bungs are hard to get i thought of getting repop caps and making the bungs on my lathe. But without the thread info it´s kinda difficult

    Checked it with a thread gauge yet?...Might match something your lathe will do.

    Are you wanting to repair a damaged tank thread? If so a bastard thread repair file may do the trick with 8 threads to choose from surely one will be a close match.

    If you're trying to fit a new gas cap, the repros often don't fit the threaded neck. If that's your problem, try to find a good original. Don't forget a new gasket.
