I tried to use this on 8mm BMW fuel lines and couldn't get a leak free join. Japanese applications might have the same issues- YMMV.

Popped right on my fuel filter

I used these on a 87-93 Mustang fuel filter on my 69 Bronco EFI. These snap on to the double flare perfectly and seem to be re-usable. The tabs could be a bit larger - they are difficult to get off with just fingers.
