The average Fuel Pressure Regulator replacement cost is between $80 and $500, depending on the car model and labor costs. A fuel pressure regulator cost $30 to $200, and the average labor cost is $50 to $300
- In some car models, you can’t replace the fuel pressure regulator alone. You may have to replace the whole fuel pressure rail.
- If you have a V-engine, you may have more than one fuel pressure regulator, which will double the cost of replacing both of them.
- In some car models, the fuel pressure regulator is located near the fuel pump in the fuel tank, making it much more difficult and expensive to replace it.

A Mechanic’s Tips about Fuel Pressure Regulator replacement
- My first recommendation is always to make sure that you will get new bolts and gaskets when you buy a new fuel pressure regulator.
- It is recommended to replace the hose clamps for the fuel lines and vacuum hose when replacing the fuel pressure regulator.
- It is not very common that the fuel pressure regulator fails, so I strongly recommend checking the vacuum line to the fuel pressure regulator before replacing it. It is also much more likely that there is a problem with your fuel pump or fuel filter.
- Check the fuel pressure with a manual fuel pressure meter attached to the fuel rail and remove the vacuum hose while the engine is at idle. If the fuel pressure moves and is within the right specifications, the fuel pressure regulator is most likely OK.
- Working with different fuel types is very toxic for your body. Always use the right safety gear for the job.
- Check in the vacuum hose connection on the fuel pressure regulator to see if you can see any fuel there. If there is fuel inside of it, the membrane is broken inside of the fuel pressure regulator.
- In some fuel pressure regulators, you can replace the membrane inside it, which makes the part cost much cheaper. However, this mostly applies to older cars though.
Fuel Pressure Regulator FAQ
Can a fuel pressure regulator be fixed?
You can replace the membrane inside of the fuel pressure regulator alone in some older car engine types. In newer cars, the fuel pressure regulator is often relatively cheap, and it is faster and more price-worth to replace the whole regulator.
How serious is a Fuel Pressure Regulator failure?
A failed fuel pressure regulator can cause your car to stop immediately, which can cause accidents if it happens at the wrong moment. If you suspect that your fuel pressure regulator is failed, we do really recommend replacing it.
How often do Fuel Pressure Regulators need replacement?
It is actually not very common that the fuel pressure regulator fails. Usually, it is caused by a bad fuel pump or fuel filter. Therefore there is no fixed amount of time or mileage when you should replace it.
How do you know if the Fuel Pressure Regulator is bad?
If you experience strange performance problems with your car together with a check engine light, there is a big chance that your fuel pressure regulator is faulty. Learn more in our article about the most common symptoms of a bad fuel pressure regulator.
