Holley electric pump need a regulator?

[Telecasterjoey]

Hey guys, I've been thinking bout my new fuel delivery setup and I don't like it. I've got a new tank, sending unit, and Holley red 5-7 psi electric pump. The way it's routed now is the pump runs inline with no return lines.

Does the pump constantly push 7 psi into my carb or will it slow once the bowl fills in the carb? Say the truck is idling and only burning half of the fuel coming from the pump where does the excess go? If I had a regulator with a return line how would it know when the bowl is full and when it's not?

I'd rather not use an electric pump but the engine I'm using is from a 1990.

Any help would be appreciated

Thanks!
