Should not be a problem as long as you have new fuel lines in the engine and not the ones from when the car came out of the factory. But worth double checking and if doubt take a look around the car for leak now and then.
Injectors: Old injectors don´t work well with E85. The new style should be OK. I´ve got the new style and haven´t had any problem so far. Been switching between E85 and regular gasoline for two years now.
