Default Fuel pressure issue

Got my pressure tested at idle a week or two ago, and forgot to post about it, haha. It was around 37-38 psi, which I know is very low. Now, before I replace the fuel pump, is there a way to test the FPR?

Like i told you over Aim.

You did not test it right.

I did the same test as you. mine was low also.
So i extended the Line and ran it inside. Then drove the car. the Pressure was right on the money then

I know, Bandit. It'* not like I don't trust you, but I just wanted to post it just to make sure. I'd like to get some more opinions.

You may trust the Badnit in this case. I instructed him properly.

My 95 SSEi ran like mad with 35psi at idle. It'* the non running psi that the FSM gives us a spec.
