Cohline Type 3024.0800 (8MM) Rubber covered PA12 (Nylon 12). Should be printed on the old hoses. The return hose on the older engines was made w/ 10MM typ 3024 but is NLA. The replacement line is 8MM.

Some use Cohline 2134 and others use the higher spec Cohline 2240. Keep digging, the data is out there....
Not finding 3024, 3124 looks to be current type. It is heat and light stabilized polyamide/nylon. Interesting that it's working pressure is reduced to 43% of rated at 80C. I'll have to check if all nylon hose is de-rated so much at elevated temps. Still should be more than adequate.
The 2134 is a no-go. Only suitable for E10, and 122F temperature. The 2240 is a possibility though, it is ethanol compatible and rated to 257F.
