EFI O-ring question

So I'm working on my '94 LHS... Apparently I did not follow proper etiquette and I took apart the fuel rail assembly. Now I need O rings for the three tube components of the assembly. I've bought two separate nitrile-type kits and gotten most of what I need. But the return line I'm striking out with.
So the question is - can I use the green type Orings from the A/C servicing kits with todays ethanol mixed gasoline?
