Here are some key details about fuel pressure regulators: Function: They ensure the fuel rail has enough pressure to supply the correct amount of fuel to the injectors. Adjustability: The PQY regulator is adjustable, usually between 60 to 85 psi, but may require spring replacement for other psi ranges. Boost Port: Many regulators, including this one, feature a vacuum boost port, making them suitable for turbo or supercharged engines. Symptoms of a Bad Regulator: Issues with a fuel pressure regulator can lead to symptoms such as increased fuel consumption, rough idling, decreased acceleration, and engine stalling. Lifespan: Fuel pressure regulators typically need to be replaced every five years.
