CJM Report: Effects of E85 after 3 years?

The fuel rails have to be removed to gain access to the bolts for the lower manifold. Well, at least they do with my billet rails, I cannot remember now with the stock ones. But I am pretty sure even with the stock rails.

I reuse those gaskets generally unless they get in bad shape.

good to know; i didnt want to spend $42 on new ones. just hope the system is easy to bleed. i hate bleeding fuel all over the place.
