Oil Pressure Guage
 

Hey guys just had a question about the oil pressure guages for these trucks. I hear its pretty important to have the right pressure to the injectors at all time. Im just wondering about the factory guage on my 05 is that enough or is an aftermarket better? Any help would be great thanks.

there are two oil pressures

one is the main engine oil pressure ( usually for a car 60 psi to 100 psi)

The injector oil pressure from the injection pump which is alot higher (hop)
on the scanner while running mine should 600 psi:hellox:

I know the gauge on the cluster is engine oil pressure

You're probably confusing pressure with fuel pressure. I'd be more worried about proper fuel pressure to the injectors first.
