Quick question: While running, fuel pressure is about 12 psi. After I stop the engine, most of the fuel pressure bleeds off within about 15-20 seconds. Is that pretty typical?

I owned a 90 K1500 5.7 for 20 years. My fuel pressure would bleed off quickly after shutting down so I think that was normal for TBI.
