Dude,
Nice gear.
Make sure that you make a bracket to support the regulator and do not just rely on the the fitting to support it - no matter what grade of alluminium or how light the reg is.
I have seen a similar fitting used to attach the reg to the end of the fuel rail that was used with no bracket to support the reg - guess what? Failed on boost, high pressure fuel and fire everywhere.
Messed up one trick looking engine bay.
