Fuel Line Upgrade

[DTSNR32]

Hey guys,

Sorry if this has been asked before but i couldnt find the answer anywhere. Im about to upgrade my fuel system with 2 Bosch 044s and a nismo intake pump. It'll also be running e85.

Will my fuel lines under the car need upgrading & what size lines should I use if i do need to change them?

Thanks for your help

it depends on what power you are planing on ? that might help people with an answer, I've been running 600+rwhp on 98oct with standard lines but that doesn't help you ..

am about to upgrade to dash 8 feed and use the original feed for the return, I know someone with 630rwhp and E85 running this exact setup.

Currently in the process of upgrading my fuel lines for E85 too. Going dash 8's, and all rubber hosing replaced with teflon.

if one standard line isnt enough you could use both the feed and return as feeds and then use the charcoal canister line (i assume 32s have them aswell?) or an old hicas line if your not running it for the return.

also a standard pump will more than suffice as a lift pump if you havent already got a nismo.

If it's the same setup that ran 117mph (as per sig) and now just going E85

Stock lines will be more than adequate.

Nah, setup has changed a fair bit now running a big single and looking to push well over 600hp in the very near future. Just want to do everything right the first time.

so what is it?

^ The setup use to be standard 26 with some -5's running 98 fuel and making a soft 400hp. Now its a built 26 with a HKS T51R, JUN plenum, ARC cooler, Titanuim piping & all supporting mods. So if I run 2x runs of -8 nylon braided line one for feed and one for return that should be suitable?

Also the rest of my lines are black nylon braid will this be alright underneath the car?

Cheers guys
