    Since your in Italy go see if you can get a 1/8 barb 1/8 npt. Pretty standard take and drill the hole out bigger with a 11/32 drill and retap with a 1/8 npt tap .

    it's a possibility... but I would like not to pull out the rrfpr... I prefer found original brass barb.

    If that's the case you need to measure the threads, do you have a tap set? the reason Im even going in this direction is your out of the country. if I were you I take the rrfpr Off and carry it with me to my local hardware store and come up with some Idea's that is of course If your wanting to run vacuum as You are.

    If these regulators are knock off of the Aeromotive style, the gauge port is general 1/8npt (which is irrelevant to what you need) and the barb fitting is 1/16npt with a barbed end. Here is a link to one IF this is the same size as Riva uses on their regulator.

    you're right.
    RIVA CREW contancted me here on the GH forum and told me that is 1/16 npt.
    they told me: I can send you one fitting

    but shipping costs and time for delivery... are orrible...
    I will try to find a 1/16 npt fitting here in Italy.

    many thanks to all.
