Perhaps a daft question but here goes.

Does the fuel pressure regulator reduce the pressure as the fuel flows in to the first fuel rail?

Or, does it offer a restriction as fuel leaves the second fuel rail?

ie, is the regulator before or after the rail?

I did think it was the latter but I've seen it described both ways now.

Cheers.

Thanks. I thought it was in the return line.
