sorry mate, I have nothing.
Makes me wonder why this option would even exist as you have an incredible variety of aviation fittings and hose available.
Just a thought; return the pump pack and 1/3 fuel rail and exchange it for AN style? (the fuel return fitting on the 2/4 side is removable so you can install a 840700 AN fitting)

Both the rail and regulator on the metric motor accept the same fitting. I have motor 4417178 and am using 3/8" high pressure rubber hose, the fittings for which took several days of search. I finally found what I needed gathering dust on the top shelf of a hydraulics service company, except the size was wrong. They found what I needed in one of their catalogues and ordered it in for me. Brilliant. I'm told they are automobile parts and the 171-06-14-BLK is (unsurprisingly perhaps) for the Bosch fuel regulator, and terminates in a threaded tail, whereas what is required for the Rotax installation seems to call for a barbed or equivalently swage-lock tail, which can be found among the hydraulic parts, good for 10,000 psi so 50 psi should be a doddle. I now know that the 06 refers to the barb size in 1/16", in this case 06/16 thus 3/8". The 14 refers to the M14x1.5. An equivalent part is STB-MLF-0614, depending on the maker's product coding.rotax-fuel-connection-0614-IMG_4551.JPG (You do not have access to download this file.)

I found the adapter I needed is made by Speedflow, part number 171 - 06 - 14-blk. You can buy online.
