Looking at the first picture, the o-ring has been cut "off center" from it not being installed squarely which caused the leak. But I do agree, ethanol is awful on older rubber fuel lines and o-rings.
I had a problem with my boat motor not turning the rpms that it should easily turn and after checking and replacing all of the obvious things and even having the whole powerhead completely rebuilt only to still be chasing the same issue, I pulled the injectors and sent them to Brucato... they were horrible from little flakes of fuel line caught in them. 2 injectors were flooding at idle and 4 injectors wouldn't flow WOT. This is with three filters/screens in the fuel system. I have since replaced the fuel lines again with PTFE steel braided lines rated for ALL fuels that we use on race cars. Methanol, E-85, leaded race fuels, even nitro blends.
I hear arguments on both sides if it is necessary or not but it seems when I mention that I use ethanol free gas to seasoned riders and mechanics they nod their heads in agreement so I'll stick with it.
10% ethanol is "Bad Juju" ... Imagine if the lobbyists/farmers/tree huggers get their way and 15% becomes the norm?
No offense but can you provide any documentation that "ethanol is Bad Juju"?
I've been hearing this for years but have seen no studies that back up the claim.
If someone can produce any type of significant evidence that ethanol harms engines I'll love to see that.
Before people start slamming me; I'm not saying it's not bad for engines, I'm just saying I've never seen any evidence that it is.

Ethanol attacks and destroys components in the fuel system ( especially rubber/neoprene ) and using it can/will lead to component failures. Check with the AMA and read about their fight to ban 15% ethanol ....
Harley-Davidson motorcycles are engineered, designed, and manufactured to run 10% ethanol fuel. On EFI motors the ECM comes from the factory set for 10% ethanol. All o-rings, gaskets, seals and other components that come in contact with fuel are manufactured from materials designed to be used with ethanol fuels.
It is ridiculous on its face to state that using fuel the motor is designed to use damages the motor.
