Going to be picking some brains for this. Other then cam and ls6 intake I'm fairly stock in the motor area, but with current gas prices I wouldn't mind swapping to E-85. But to do this will I need to get rid of the steel tank from my 98'. Was reading through this.. https://ls1tech.com/forums/showthread.php?t=602091&styleid=27

 

So what exactly are you asking?

 

What is needing to be upgraded to run E85

 

New pump and injectors that are e85 compatible and id replace the rubber section that goes from the hard line to the rail with something that is ptfe coated

 

So I won't have any issues using my factory steel tank?

 

Sorry, you had said you were already going to replace that. E85 attracts water which causes rust. I think the steel fuel lines are alright but I would probably swap in a newer take since you have to pull it to replace the pump anyways

 

No I was asking in the OP if I needed to replace it

 

I would seriously consider replacing it due to the humidity in your area and the effects of e85 on non stainless.
