Ok, I am installing my NOS system probably sometime this week. However, where do I install the fuel pressure regulator switch? In the manual it says to find the fuel rail test port fitting and install it there. But the Maxima does not have one. So it says you can alternatively install it in the fuel filter. Where is the fuel filter at and was it hard to install it? Also, where is the fuel pressure regulator at on the Maxima? Thanks all.

 

didn't u just got rid of ur nos not so long ago erik?

 

this is not a flame. But if you dont know where the fuel filter is. Should u be installing nos?

 

I had the other NOS kit in my trunk, but cough cough money was tight back then, you remember? Well, I went ahead and got in on that great deal from JC Whitney.

infinitiblast: I have looked around in the engine compartment for about 2 hours and cannot find it. I do not have an owner's manual with the car so that is no help. And I do know what I am talking about because I do work in a garage, but different car manufacturers put fuel filters in many different locations.

 

The fuel filter is mounted on the drivers side firewall behind/benieth the throttle body area.
