Can some one tell me what fuel pressure should be on 05. 4.7 v8

I’m having rough idle , hard starting when warm, 12 mpg and smells like fuel out of exhaust. Also fuel gauge is jumping around a bit!

I tested at port. 50 psi. 2 min later was at 30. Key off

Then key on was 50 psi 40 psi after 3 min. And 18 psi after 14 min.

Fuel pump? Leaking injectors?
