I acquired a Rivarossi 2-8-8-2 that had been upgraded with a can motor.

The motor is mounted a little cockeyed, and a flexible drive shaft is needed. There is not enough room for those Delrin connections.
The rubber hose that was in place has worn out. I have tried week eater fuel lines with a 1/16 i.d., but it is a millionth of an inch too large.

Does anyone have an idea for a replacement?

I think heat shrink tubing would not be durable enough but have not tried it. Surgical tubing does not seem to be made in that small of a diameter.

Check at a hobby shop that caters to model airplanes and maybe a fuel line from a model airplane gas engine would work for you...?

Walther's once sold flexible drives for some of their earlier diesel locomotives.
