While technically a car can operate without a fuel pressure regulator, it is not recommended. The fuel pressure regulator is responsible for maintaining a consistent fuel pressure to the injectors, ensuring proper fuel delivery and engine performance. Without a fuel pressure regulator, the fuel pressure could become too high or too low, leading to a range of issues including poor fuel economy, decreased power, and potential damage to the engine over time.

A failing fuel pressure regulator can cause a number of symptoms, including poor fuel economy, decreased power, rough idle, and even stalling. You may also notice a strong fuel smell, fuel leaks, or black smoke from the exhaust. If you suspect that your fuel pressure regulator is going bad, it's important to have it checked and replaced as soon as possible to avoid further damage to your engine.

The cost to replace a fuel pressure regulator can vary depending on the make and model of your vehicle, as well as the brand and quality of the replacement part. On average, you can expect to pay anywhere from $50 to $200 for a fuel pressure regulator replacement. Don't forget a fuel pressure regulator adapter or any other fittings to go with it. However, it's important to keep in mind that neglecting to replace a faulty fuel pressure regulator can lead to more serious and expensive engine problems down the line, so it's best to address these issues as soon as they arise.
