I went outside and it started right up it’s just under 30 psi right now running

That's just barely within specs. Did you read the 2 linked articles? Does the fuel pressure rise when you disconnect the vacuum to the FPR?

no I just removed bed
where is vacuum to the fpr?

no I just got bed removed
highest I saw was 30 psi and it would leak to 20

what is this line under the bed go to?

where do I disconnect vacuum to for?(

Less than 8000 miles ago and less than a year ago barely
I changed filter

The FPR is on the fuel rail, not in the back. Post #14. Review the whole thread, we discussed the FPR.

If it won't go over 30, you have an issue, fuel pump may be on its last legs. I don't know where that line goes.

That line he's pointing to is the rear diff vent hose.

I removed bed and replaced fuel pump

Now do the FPR test. Pull the vacuum line and the pressure should go up at least 5 psi. If you can't get at the FPR easily, follow the vacuum line back from it and pull it at that end. Review the whole thread. Clear the codes and see if they come back.

I can not get to or find the regulator.

walked outside my gauge showed 0 until I turned key on. Maybe my harbor freight gauge is leaking I’m checking. I can’t find the regulator I believe I disconnect vacuum to egr valve

This video may be key
Everyone else online was saying It was on the driver side

I just installed a brand new pump unit from Oreillys today.
i cleared codes and drove about 20 miles.
it runs about 30 psi
i believe it drops after a few hours of being off until I turn the key.

ok I read links
i installed new pump unit
I turn key it goes to about 30 psi
i believe a few hours later when I return it will be 0-10 psi until I turn the key on.

I haven’t confirmed the psi specs via google.

also can’t exactly see fuel pressure regulator

prior to changing unit seems I’m 10-12 mpg

why do we think I need to unplug vacuum to regulator ??

The FPR is on the fuel rail that sits on top of the injectors, pictured in post #14. You need to unplug the vacuum to see if it's operating properly. If it's leaking it's sucking gas through the vacuum line into the manifold, there will be gas in the vacuum line.

Specs are 28 to 40.

I can’t access this at the moment maybe when I remove battery and numerous other parts according to that video it’s posted. I’m at 30 psi after changing pump unit how long should it hold 30 psi before dropping? Maybe if I knew where other end of line plugs in it would be easier or doable.
