That intake looks great. Mine was painted Mercruiser red all over. Good luck with your retrofit.

If you are planning on using the stock injectors, I had a set flowed and they came out at 25 lb/hr at 43.5 psi. Comes out to 28.9 lb/hr at 58 psi (4BAR) which is the pressure the marine regulator outputs with with the vaccuum reference unplugged. Plugged in pressure comes down to around 52psi.
