Engine/Transmission (1998.5 - 2002) hows this for fuel pressure

[gottorq33]

with a carter pusher at tank and bigger line kit and banjos from diesel dynamics with mach 5's and edgecomp I idle at 20psi cruzing at about 65mph psi at 15 and at WOT ABOUT 8 OR 9 should I be concerned or ok

Sounds about right with the bigger injectors - and your minimum PSI still seems adequate. My similar setup without larger injectors ran 22 PSI at idle, 20 at cruise, and never lower than 16 or so at highest loads or Comp setting...
