That breather filter may drip oil onto your manifold after the engine has been worked hard on track
I would extend it with a length of hose to prevent it dripping,maybe heat shield it
or use a short 90 degree bend so the filter is vertical and cant drip oil
and is that blue hose fuel resistant and able to cope with fuel pressure
sorry to pick holes in an awesome car and if I have stated the obvious regarding the fuel pipe
just I study pictures (for ages) and see things sometimes and feel the need to comment
