You said you were keeping the stock routing I think, which runs the lines on the pass side, is it close to a header? But if you mount on the regulator on the firewall, passing by the header isnt an issue... my single -8 feed line runs on top the pass frame like stock but come a little closer to the header than Id like, its got heat wrap on it and didnt have any issues without the wrap, but adding a return next to it on that side will get too close for comfort.

Looking forward to pics & info as you install it.
Tanks said that 3/8 would be adequate for all the lines. Is that not correct?

I think I should be able to keep the lines away from the exhaust. I'm running RA manifolds so I should have more clearance than with headers.

I’m trying to plan a similar project for the winter and I’m trying to understand whether 3/8 feed is good for under XXX hp vs going up to 1/2”

A lot of what I read has people saying things like go to 1/2” so you have reserve, etc, I’m just trying to understand what’s right vs “might as well”
