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.
