28-29,000 PSI... The mini maxx uses KPSI or KSI (can't remember) and for every one of those units it is 1000psi. at an Idle my truck sits at 3.8-4.0 or 3800-4000 psi of pressure...

That's insane. I had no idea that the fuel pressure was that high on these engines.

Thats why you need to be super careful around HP fuel rails!!! Alot of newer engines also hold rail pressure once the engines shut down, theres special procedures to bleed off pressure to work on the fuel systems.
