So here is what's been happening. I recently bought a Nismo FPR type B with the adapter and a fuel pressure gauge. I installed them today and this is what is happening.

When I put the car on the on mode, the gauge tells me that the fuel pressure is above 60. My gauge only goes up to 60. When i start the car, the fuel pressure gauge starts to go crazy! So I figured, maybe the pressure was soo high that the gauge couldn't take the pressure. So I quickly turn the pressure down and goes down to like 25 psi. At this point, the car wants to turn off since it's not getting enough fuel. I try to turn the pressure up to the stock 36psi but right before it reaches 30 the gauge starts to go crazy again! I have no idea whats wrong with it so I thought maybe someone in here could help me out with this problem. I will post a video and some pictures of the problem as soon as I upload them.

Can anyone help? ?

Needs to be 45 with the vacuum hose OFF...

The hose vibrates, is the pump pumping or just dying?

Yeah the hose vibrates and I have no idea why. It continues to pump but as you can see the needle on the gauge goes crazy. Here is a picture of how i did the set up.

The green lines are the hoses, the red is not the fuel rail but a metal line, then blue 1 is the fpr, blue 2 is the gauge, blue 3 is the adapter and blue 4 is the fuel rail. Anyone see any mistakes here?
