My fuel pressure gauge usually registers 35-38psi when idling on an 'up-to-temp.' engine. Sometimes it hits 40psi at idle when sitting in traffic with the A/C and associated fans on. At WOT the gauge is buried at 100psi. It's been that way since the install back in Jan 2005.
CLS-6; HBP; 100k miles with 55K on the blower.

Use the Search for 'fuel pressure' and finds tons of info.
