Oh, ok so I just have to go and but a gauge and undo that cap? Are there any specif instructions? Mine just acts finny at idle sometimes and I would like to know of its a vaccum leak or maybe low fuel pressure.

Thanks Bill
When you get the Gauge it will having instructions in it,
But this is how it goes, Screw gauge onto the fuel rail, turn the Key to on, Bleed out the air, check for leaks(Gauge), Start car, Bleed more air out, then watch the gauge, see what it reads. Reve it up and hold it a few times...

If you want a pics of the Gauge let me know ill post some.

Why are we mentioning the incorrect way to test fuel pressure?

FSM says put gauge on, turn key on and off, bleed air... then turn key on and off a few times to reach maximum pressure. Watch gauge for 10 min to see if any bleed down occurs.

Says nothing about starting car. If you have issues at higher rpm..then I suggest lengthening the hose and watching FP while driving.

And at 40.. it'* within an acceptable range. If you suspect further problems.. drive and watch FP.
