What does the vacuum line do on a fuel pressure regulator?

A vacuum controlled fuel pressure regulator contains a diaphragm that moves with fluctuations in vacuum pressure. When fuel pressure at the regulator is high enough, it overcomes the spring's pressure without any vacuum assistance. However, at idle, the engine's vacuum is high and assists the valve's opening. via

How much fuel pressure does a TBI need?

The fuel pressure regulator is set for approximately 12 psi (30 psi on '94 & '95 BBC trucks). With a service range of 9 to 13 psi being considered good. via
