E85 in 90 240sx with redtop sr20det? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, the search in this website isn't working for me, so sorry if this is posted somewhere. I have a '90 240 with a redtop sr20det. The entire fuel system is upgraded except for the lines. Can the factory lines handle E85 or do you need to upgrade them?

You'll be fine, the factory fuel lines should handle at least 5-600hp on e85.

You can use factory Lines.. but since you already "upgraded" the entire fuel system to be e85 friendly might as well get some hardlines or Teflon lines with fittings and know that everything is good.

The factory hard lines will handle enough fuel flow for 5-600WHP, if you are looking for more power upgrade to 3/8" Hardline or -8AN. the factory return line has been good for over 1000WHP from our experience.
