Hi, I am Mike, welcome. I'm reviewing your question.

Expert:  Mike S. replied 1 month ago.

That is too high, supposed to be 60-66psi. Check for a kink in the metal fuel line causing backpressure.

If there are no kinks in the line try a new fuel pressure regulator and check the fuel pressure again.
