[750hp]

I'm intrigued by the fuel system inside your rear wheel arch.

Is the top black hose the return line from the fuel rail?
Does it then flow to the regulator and T into the inlet of the fuel filter?
From there, does the filter flow straight to the engine?

If so to all of the above, I'd be concerned about the regulator getting pounded by stones and debris, and I'd worry about the fuel not making it back to the tank to dissipate some heat across the larger volume of fuel.
I'm also not sure of the benefit/detriment of having the regulator so far away from the engine.

Yay, another build thread is starting!!!!!!!!!
