A fuel pressure regulator helps maintain the fuel pressure in the Electronic Fuel Injection System. If the system needs more fuel pressure, the fuel pressure regulator allows more fuel to go to the engine. This is important because that is how the fuel gets to the injectors.
Do you need fuel pressure regulator?
The fuel pressure regulator is necessary for the proper running and optimal performance of the pressure and the car's internal fuel system, providing the injectors' required support.
How much does a fuel pressure regulator cost?
All together, the total cost of a fuel pressure regulator will run somewhere between $150 to $350 in most cases but it can easily go above $500 for electronic fuel pressure regulator replacement. To save money, it's recommended to have an independent mechanic or repair shop do the work versus a dealership.
Where is the fuel pressure regulator located?
A fuel pressure regulator is located at the end of the fuel rail and it connects to the injectors of the car. To locate the fuel regulator, you must first find and follow the fuel rail in your engine and you can find it at the end, before the fuel gets into the engine.

What causes bad fuel pressure?
Typical causes for low fuel pressure include a dirty fuel filter, weak pump, incorrect tank venting, restricted fuel lines, a clogged pump inlet strainer and faulty electrical control.
How long does it take to change fuel pressure regulator?
5 hours is the amount of time a professional mechanic would need. It takes about one hour if the regulator is replaced.
What will happen if a vehicle has a leaky vacuum diaphragm on the fuel pressure regulator?
If the fuel pressure regulator's diaphragm, or any of the seals fail, fuel leaks can occur. A fuel leak will usually produce a noticeable fuel smell, and may also cause engine performance issues.
Does a fuel pressure regulator increase horsepower?
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.
Do electric fuel pumps run continuously?
Fuel pumps run continuously once the engine starts; and continues to run as long as the engine is running. The pump may run at a constant speed; or variable speed depending on engine load and speed. If the engine stalls; the (PCM) will detect the loss of the (RPM) signal and turn the pump off.
Can you drive with low fuel pressure?
”It is not safe to drive with a faulty fuel pump because when a fuel pump is faulty, it can no longer supply the fuel system with constant fuel pressure and your vehicle won't start, it can stall, or even completely shut down at any time.
Can a fuel filter affect fuel pressure?
Fuel filter problems can also cause the Check Engine Light to come on. Some vehicles come equipped with fuel pressure sensors that monitor the pressure of the overall fuel system. A clogged fuel filter may cause low pressure, which will set off the Check Engine Light to alert the driver — if detected by the sensor.
