Hi Tom,
From our previous discussions.. and a couple of updated pics further down from today.
Under seats.. Supply is in aft position using stock location of fuel line with TCW fitting.
Brakes middle, and return is forward position using a custom position above and aft of the stock supply location also with a TCW fitting.



This and below is from today 2/25/24
It’s hard to get a decent pic because the forward part of the tunnel is in with the panel etc..
Supply line is aft and going to upper chambers of valve.
