How does a return style fuel pressure regulator work?
As pressure increases, it pushes against the spring through a diaphragm. When the pressure gets high enough, the bypass valve starts to open. This redirects some fuel back to the tank. By doing so, the regulator will adjust fuel pressure based on boost pressure.
Do you need a vacuum line 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.

Does increasing fuel pressure increase power?
The noob belief amongst amateur tuners is increasing the fuel pressure up a few psi from the regulator will mean the injectors are getting moaar fuel which will increase the horsepower. Wrong. Truth be told, aftermarket FPRs are not necessary and the factory OEM FPR will do the job just fine.

Does a fuel pressure regulator go on the feed or return?
No. The fuel pressure regulator must be after the fuel rails. There’s no fuel pressure after the fuel pressure regulator, because that’s the return side.
Why is a vacuum line attached to a fuel pressure regulator?
The fuel pressure regulator uses manifold vacuum to increase fuel pressure during hard acceleration, and the manifold pressure is low because the throttle plates are fully opened.
What is the purpose of the vacuum controlled fuel pressure regulator?
Fuel pressure regulators are a vacuum operated spring-loaded diaphragm that enables a vehicle’s fuel delivery system to maintain a constant pressure. When the vehicle is at idle the regulator is open allowing fuel to bypass the delivery system and go back into the tank.
