E85 fuel lines?

[YEEE85]

Im planning to run E85 in my '85 GN with ported iron heads and Work 5857 turbo and ported intake, 3" DP, 3" single shot exhaust and of course all other supporting mods-
Will the stock fuel lines be good enough for the increase in required fuel volume?

No.
PTFE is the most logical choice.
Not cheap, but very reliable.

I'm more concerned with the size of the lines- are stock lines fat enough?

The stock return line can really get in the way. It can cause fuel pressure to be excessively high when you need it to be low (at idle / decel).

Best route is to go with larger lines, -8 supply and -6 return. The racetronix line & filter kit is popular. Their hellcat pump setup with wiring will also do the job well into the 10's or even better. Full throttle speed carries this stuff, or go to racetronix site.

E85 requires 30% more flow.
The return line is the more restrictive. The connections at the ft of the frame are also restrictive as they're a "Saginaw design" with o'rings.
Obviously, the more power, the closer to running out of flow.
Your choice... Try it with what you have.

In addition to the above
I would seriously consider doing the ptfe lines and rail.
The stock lines and rails are very old and I've seen them in bad shape on the inside
I would flush them and flow injectors and see what's going before you try to use them.

I agree with all that has been said above.
Went to 85 myself a few years back, & went with the Cruz set-up. -6 & -8 lines filter included. Plus filter is cleanable according to Don.
Ran over axle, along DS frame rail, & up to motor.
