The pressure regulator (spring) is on the side of the secondary fuel filter (the one under the hood).
The link to the thread at The Diesel Garage no longer works since someone "hacked" their database and deleted all the old threads. I will find you the proper link and post it later
Here is the proper link (note - the pics were lost):
I too noticed last night that my Nordskog sending unit is scaled wrong, comparing it to my mechanical gauge. So the egauges/isspro unit is back under the hood. Roughly, a 20psi change on my mechanical gauge only registered as a 14psi change on my nordskog unit.
When I put the bb back in the regulator last night, I didn't realize that the plastic air bleed fitting had fallen out of the filter housing. When I put it back together with the BB I was only seeing 40psi at idle on my mechanical gauge. I then calibrated the Nodskog fed Commander to read the same 40psi. Then I took the regulator apart again, noticed the plastic air bleed fitting was missing, replaced it, and buttoned things back up again. After that, my mechanical gauge was reading 60psi, but the nordskog fed commander was only reading 54psi. Trying to bleed air from the sensor line did nothing. So without a doubt, a 20 psi change on my mechanical gauge registered as a 14psi change on my nordskog sending unit. So I threw my isspro/egauges sending unit back in, calibrated the Commander to read the same as the mechanical, and called it a day. I just didn't feel like pulling the plastic air bleed fitting back out of the regulator again to test the egauges sending unit the same way.

Ok, can you guys expand on this regulater and fuel pressure guage topic. I started a new thread titled fuel issues because of how my truck has been acting. What you guys have been talking about here sound like it might be related to my problem. Mine has been acting like it is out of fuel, first at 1/8 tank, and now the last few days at 1/4 tank. I am thinking maybe fuel pump is bad, and if it is am thinking about replacing it with something that can provide more pressure. I haven't done any mods other than intake and exhaust, but am thinking about going all out in the near future. I am so sick of hearing so much negative about the 6.0's, I have been a die-hard ford guy for so long. But, I do want to put my time and money into something that will hold up to my expectations. Any comments...suggestions....Thanks!
Definitely going to start with the egr cooler delete, probably head bolts at the same time, then tuning, turbo upgrade, trans if necessary. I have pondered the idea of a cummins swap, but not sure if it would be worth it. I'm not planning on any sled pulling or any competition, just want it to be reliable long term. I learned in another thread that I may have an issue with my fuel tank if it is metal, and the lining may be breaking down and plugging things up. I am hoping the pump isn't bad, but if it is, should I just replace it, or go to an aftermarket performance pump? My biggest gripe about this 6.0 is the fuel mileage and not being able to do any performance upgrades in fear of it coming apart. My other option is trying a girlymax or the other bad word.
Come on, I'm sure everyone has some opionions......
Are we talking full turbo upgrade or just a rebuilt stocker with(hopefully) better parts? If we are talking about a full upgrade to a bigger turbo, I would suggest upgrading injectors with an RR kit as well.

If you are going to be doing a full turbo upgrade which would call for upgrading injectors to spin that new turbo, I would just get an aftermarket pump to take care of that. The stock pump can handle mild injectors, but since you would already have to replace it(if it is determined that it needs to be replaced) then I would just go with aftermarket, but make sure that the pump that you get as a spring for 60 psi. The two more popular choices for pumps are FASS and AirDog, both are essentially the same, and I'm pretty sure you still have to ask for the bigger spring.

Here is the problem the mods that you are planning are performance based mods, you might see mileage improvements, but you might not or they might be slight. Certainly won't be worth the price of the mods for a few years. Don't do performance mods for mileage, more then likely you won't like the outcome.

6.0 is one of the most "misunderstand" engines. Either you do the installation of the mods right(or get a reputable person to do them), don't cheap out with parts and you should have a very good truck.

Thats what I have been hoping to hear. I have to admit, the mileage is not the main objective! I do want to have the reliability, and am getting sick of all the negative rap the 6.0's have. I have been die hard ford almost my whole life, but for the first time have been considering something else, just because I want to have something I can rely on. I shouldn't be worrying too much, other that this fuel problem, it has been an awesome truck. I just want to be able to do all the upgrades to my truck, but don't want to be spending it on an engine that won't live to enjoy it. Sorry so wordy, but does that make sense? Thank you for your advice. I will be keeping up on this if you don't mind?! Thanks again
