    In hose size terms...its -3an line..if that makes sense.
    May be metric. Not sure. I have a line coming of mine to a gauge and its a -3.

    Could be 3/16..thats what the summit site has listed

    I did this a few years ago and wasn't able to find an adapter. What I ended up doing is getting a 1/16 female NPT nut to 1/8" tube fitting, installed a short piece of tubing (1-2 inches long) and had a 1/8
    tube to 1/8" NPT nut on the other side.

    This has worked well for me for about 4 years now.

    Good luck. You can unscrew the scrader valve and test your newly purchase fitting before you do all the work.

    1/16" NPT - only place I found them was a Summit, Jegs, etc. I bought mine from Earl's at WFC last year.
