Hello,

The fuel pressure regulator is located in the fuel tank attached to the fuel pump. You must remove the tank to replace it, here is a guide that will give you an idea of what you are in fro when doing the job.

Here are some diagrams (Below) so you can see the location of the regulator and how to get the fuel tank out. Luckily you have a trap door in your car so you don't need to drop the tank. Take a look (below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

We purchased a new fuel pressure regulator from the nissan dealership. He gave us a diagram as to where it should be. We cannot find it under the hood. Can it be near the gas tank

On the 4 cylinder engine this regulator is part of the pump assembly. I am going to attach the info below.

However, here is a guide that will help with this.

Please see the info below from the manual that will give the location of the regulator and the process on how to replace it.
