fuel pressure? time for lift pump?

[cycletech]

I have a 2005 2500 5. 9L. . My fuel pressure between factory filter housing and a separate 2 micron filter is reading 10-11psi at idle when cold and about 5-6psi when warmed and driving. I still run the factory fuel separator and have an xx fuel filtration set-up with 10 micron sep. and 2 micron fuel filter running before factory housing. Rail pressure is normal and do not fill any loss of power. do you think it is time to upgrade fuel pump. . obviously this still has factory lift pump in tank. . no power adders. .

Sounds fine to me. If you have a doubt, run the fuel line (after all the filters) into a bucket and test flow rate. You don't need a lot of pressure, just good volume. I see no reason to change anything on your set up.

I have the same setup and run about 400rwhp on the stock pump and have no intentions of upgrading any time soon. 9psi at idle, 5. 5ish WOT.

As long as the pressure stays above 3 psi cruising it should be fine.

Yea, those numbers sound normal to me too.
