I got the answer below from an engineer at Saint Gobain. In my experience, it will last for at least several years.
If you don't mind opaque black like the stock tubing, Viton might last longer. McMaster-Carr has Viton tubing in a variety of sizes:

Jim,
Tygon F-4040-A is compatible with pump gasoline that contains ethanol. Although it is compatible, because it is a plasticized formulation you may eventually notice the tube get stiffer as the plasticizer extracts which could eventually lead to cracking. It is impossible to estimate how long that would be as it depends on the application and environment how long it would last before needing to be replaced.
Any other questions let me know.
