I have two separate fuel systems which are connected with a Pollock valve. The Pollock valve allows for fuel to return to either the right or left tank. My problem that I just realized that since there is a continuous flow of fuel there is no pressure for the Webers. I believe I am supposed to have about 3 pounds of pressure facilitate the Webers. If the fuel is continuously flowing around there is very little pressure. Seems to me there has to be a restriction somewhere to create the 3 pounds of pressure. Any ideas on how to create the 3 pounds of pressure.

It sounds like you are using half a system.
Normally with carbs the fuel goes from a tank through the fuel pump filter and pressure regulator and non return valve then straight to the carb. Without a return line to the tank.
On a fuel injected system you have the tank through the pump, filter pollack valve to a swirl tank and ther overflow from the swirl tank goes back throughthe pollack to the tank.
Fuel is then drawn from the swirl by a high pressure pump to the fuel rail and hp regulator and returned to the swirl.
What you are describing is a half way between the two
