E 85 fuel lines


Wondering if someone can give me some advice on e85 fuel lines on a 87 gn . Im changing over and replace my fuel pump with a walbro 440 . Scott from cotton's told me i need to increase return line size due to the output of this pump. He tells me I need a 6 line. I have a stock fuel rail. Was thinking of using main line for return and run a completely new main line. Can i do this and if so what will i need to connect with stock fuel rail? Or is there a better way to doing this.


If you run new line use a 10 or an 8. Depending on your performance needs.
Also use a Teflon line. Orme brothers is my choice to deal with, Joel is very knowledgeable.

Using orig feed line as return is OK as long as all is in good shape! Reverse filter or eliminate!! Make sure to confirm all at sender!! Any quality #8 (teflon) line will suffice as the new feed with proper fittings at rail and good fit at sender. A lot depends on how you choose to run the feed line determining the fittings needed................
