I believe this is incorrect. The FXi is basically an FX and many of the parts will interchange. Biggest difference between AX and FXI is the number of head bolts.

After spending the morning trying to find a needle valve holder, it seems indeed I was wrong. What appears to be the same remote needle as the .46AX isn't. The FXi uses the 65LA's needle valve holder.
Talk about making parts shopping fun.....
