What is a vacuum 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.
How does a vacuum pressure regulator work?
A Turbosmart FPR works by bleeding off a portion of the fuel flow to the injectors from the fuel pump to control the fuel pressure. Fuel is pumped from the fuel tank to the fuel rail by the fuel pump. The FPR is normally mounted after the fuel rail. This ensures that the fuel rail has priority in fuel flow.
Where is the fuel pressure regulator located on a vacuum biased port fuel injection system?
Fuel-pressure regulators on fuel-return-type fuel-injection systems are installed on the downstream side of the injectors at the end of the fuel rail.
How does vacuum affect a fuel pressure regulator?
A vacuum controlled fuel pressure regulator contains a diaphragm that moves with fluctuations in vacuum pressure. The opening valve lowers the fuel pressure at the rail by allowing more fuel to circulate back to the tank through the return line. A kinked and restricted fuel return line raises pressure at the fuel rail.

Are there still vacuum hoses and tubing in cars?
Older vehicles relied on vacuum hoses and tubing for a wide range of automotive needs. Modern vehicles have passed many of these roles onto more efficient electrical systems. However, your car may still have vacuum tubing for your PCV valves and brake boosters.
What kind of hose fittings do AutoZone have?
AutoZone has a wide selection of hose diameters and various fittings for each type. From straight couplings to t-shape and y-shape connectors, you’ll find everything you need to repair your worn-out tubing. Because vacuum tubing is made of rubber, regular use will wear it out over time. Extreme conditions can cause it to wear out quickly.
Do you need vacuum tubing for brake boosters?
Modern vehicles have passed many of these roles onto more efficient electrical systems. However, your car may still have vacuum tubing for your PCV valves and brake boosters. Just like your power steering system, your brake boosters are essential to keeping you safe while you drive.
