They should be shown in the parts book for your year. Having said that, I just looked for the one for my '48 A7 in my book and it is not obvious which is the image for part 67-8025. There is a picture of a 2 into 1 assembly which is probably what mine should have but it is not labelled with the part number. I have wondered about reinstating the original solid copper fuel pipes but was not sure how safe it would be if they suffered fatigue failure from vibration.
