Default E85 and rails

Are there certain fuel rails that will not hold up to e85 or are better for e85? All fuel rails basically built the same and just pick which one you like the best?

Are you concerned about material or volume? The metals will really give you no problems but with some stock style or production rails you could run into some volume issues on higher output builds.
Thank you,

I was more worried about the material as I am looking at some aftermarket rails for my E85 turbo build. This will be my first E85 build and hate buying things twice

There were tons of flex fuel optioned LS engines. They didn't use different rails.

You will have no problem with the materials. Keep in mind the volume requirements of E85 vs. basic Petroleum based fuels. I have never seen an aftermarket rail with less than a -8 inner so you should be OK there. I would feed the rails on both sides and run a T with your return at the end of the system to ensure you do not have any fuel starvation issues.

How much power are you hoping to make?
