Fuel pressure drop

[TitanSvt]

Hey all, looking for some advice on how to test my issue.
Issue: Fuel pressure drops to 0 after about 2 mins after shutoff.

Need help with how to test where my issue is? I don't have any fuel leaking but from research, I need to test the: injectors, fpr, or fuel pump check valves.
Any way to test these items?

For reference:
It's a Fore lvl 4 return style with 3 x Wlabro 450LPH pumps (TIA485-2 F90000267)
ID 1050x injectors

Thanks for any help!

That's normal. I have the same pumps and they act the same way. I bet pressure comes up fast as soon as you turn the key on.

It doesn't have a PPRV, so yes it's normal.
