i have a 1999 GMC Sierra with a cammed 5.3 and I wondering if there are any companies that sell E85 kits.or what would I need. I know I’ll need new injectors, fuel pump, new lines, pcm flash. Would I need anything else, where would I get everything

Just a pump, injectors and a tune is required. The factory fuel lines are metal, you don't have to replace them and they will flow way more fuel than you would require on a cammed engine.

Filler neck isn't, on mine at least anyway.

Why would the filler neck matter?

Rubber may degrade over time or may not be able to handle it

Show me a documented case and I'll believe it

Ive run e85 on a '93 Saturn system, bone stock everything except a 255, never an issue

I run e50 in a '91 MR2, completely stock everything and its been fine

I dont buy the hype of "e85 and incompatible materials." How many parts do you clean with rubbing alcohol/IPA, and never had an issue? I let e85 sit in a plastic bottle in my hot *** shed for well over 2yrs, and the bottle was still fine and pliable, and we still use that bottle for oil and trans fluid capture.
