High pressure fuel pump?????

I took my truck in to be scanned (I do this twice a year to all my vehicles) and they said everything was good other than I was running 10psi low on the high pressure fuel system, they told me it was not a big concern right now and not to worry about it.

My question is what would cause this and how could it be fixed?

i'm not a 6.0 person, or a tech, but i would have someone else look at it. imo 10psi is time to start planning for a pump possibly.

High pressure oil?

They told me that the low pressure side was good and it was the high pressure side that was low.
I thought there was only one fuel pump on the 6.0

From what I am reading, I think you are confusing two different fluid systems. There is only one fuel pump on the 6.0 it is called the HFCM- (horizontal fuel conditioning module)
The HPOP (high pressure oil pump) feeds high pressure oil to actuate the injectors.
The LPOP (low pressure oil pump) supplies oil to the HPOP reservoir and to all the friction bearing surfaces, piston skirts etc.
If it is 10 psi low on fuel pressure, you will be damaging your injectors in short time. You need to find out which system is having the "low" pressure condition. Is the truck running ok?

I believe the code your getting is for the HPOP being above or below desired levels The code number is a P12??. Which the code would be caused by your programmer when your on the throttle hard.

If the truck is running good and healthy. Then I would leave this code as being activated from the tuner.

I am thinking of the fuel system not the hpop system.
Is it possible my HFCM could be full of s**t?

It runs fine with no codes.....I would have thought I would have noticed a 10psi drop in fuel pressure.

Do you have a fuel pressure gauge?
