Su carb specs (help!)

Since my last post, I deciced to go with early SU carbs in my ongoing restoration of my '73 240Z. Yep, we got the '81 280ZX L28 going in next week. Since I'm using a P79 head, I must go with an electric fuel pump. I need to know:

Which pump to get; Brand, psi, and gallons per hour.

And do I simply regulate the line, or do I double regulate right before each carb (leaving the system un-hindered thus avoiding possible vapor lock)?
