Hello,

On this the fuel pressure should be 47 PSI at the fuel rail and maximum pump output should be 92 PSI.

There is a port on the fuel rail that you can attach a pressure gauge to check the fuel pressure.

Here is a helpful video:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
