    1997 Chevy K3500 5.7L. What should the fuel pressure be? When I ran a test with a presure guage it topped around 60-62. A few seconds later the pump shut off after making pressure and the guage dropped to 20 psi and held steady. Does this sound right?

    yes that sounds about right it uses a higher pressure to prime the system then kickes down to a maintnance level.
