Hello,

The fuel pressure regulator is part of the fuel pump assembly. This vehicle does not have an inline regulator.

This vehicle should have 51 PSI of fuel pressure at idle.

Here is a helpful guide:

I have attached the fuel pressure test procedure below.

Let me know of any questions.
Thank you.
