Fuel pressure numbers
Got my fuel pressure gauge installed today. It is installed at the injetcor pump intake.
Idle -- 11 psi
WOT -- 9 psi
Cruise -- 10 psi

If I remeber right, those numbers are good.

How low is too low?

Thanks

Your ok but possibly loosing your lift pump. Keep an eye on it.

A stock 2002 with new lift pump will average 15 at Idle, 12 at cruise and 10 at WOT, if I remember correctly.

How'd you get a Dodge dually into Germany

According to the manual 8 PSI is the bare minimum for a 2nd gen 24v.
