Where to Find Correct PSI Fuel Pump?

[flathead34]

I've read and heard that the correct '33-'36 fuel pump should have a pressure of 2.5 to 3 PSI. I tested the pumps I have for my '34 and they ranged from 3.5 to 5 PSI. I have had some carb issues (leaks) that may be caused by a too high pump PSI. Where can I get fuel pumps with the correct PSI? Does any one rebuild them with the correct pressure. Happy V8ing, Mike
