I'm pulling my engine and while I'm opening up the fuel lines I figured I might as well replace the stock rubber lines in the engine bay. I'm having trouble figuring out exactly what I need.

Car runs E85, base fuel pressure @60psi running a boost referenced fpr eventually around 20psi MAP. I'm having some trouble identifying what's ok with ethanol and finding a lot of stuff says 50psi WP, 250psi burst pressure and not sure that's safe at the pressures I'm running.

 

iirc any modern fuel line past like '96 or something is teflon coated.
that's what you want, the coating. and since they started blending e into regular gas probably around that same time, I'm betting there is no such thing as un-coated modern fuel hose/line

 

Thanks for the reply. I read so much contradictory stuff on E85. FWIW, I've been running it on the stock lines for a year and half now and haven't destroyed anything. But I'm still a bit paranoid of it.

Of course I search for an hour, give up and post, then immediately find what I'm looking for.

I'm using PTFE (Teflon) coated hose for my braided stainless AN lines.

 

Are you running all AN line?

 

If the rubber lines are old, replace them with Ethanol compatible rubber from Autozone/Napa and don't worry about it. I've been running E85 in my 92 for 3 years now with no issues on otherwise stock lines.
