    Fuel blocks? If they are tapered pipe threads they will be NPT, not common in Oz but findable. Similar to BSPT but usually a slightly different TPI.
  • It’ll be 1/8” NPT where it threads into the carb, then it’s 5/16 flare
  • That is a coincidence I have just taken delivery of the following from Rockauto:


    This is 1/8 NPT male to 5/16 pipe thread (1/2 x 20 UNF) elbow, to fit the rear WA1 carb on a twin H set up.

    Delivery to the UK was only a couple of days, maybe they ship to Oz too.  I ordered up a number of other things from Rockauto as well, so well worth browsing through their listing for Hudsons.

    Hope this helps.  Regards, Brian.

    If you are talking about the tee.  It is 1/8" male npt at the carb and two female to 5/16" inverted flare (1/2 x 20 UNF).  I had difficulty finding them even online.

    I scrapped the stock fuel lines and put in stainless steel Swage fittings.
