Lots of good stuff in there. I'm gonna have to read it a few more times and post highlights.
Bell Performance has lots of good fuel articles. It would be nice if they would combine all of them into a master reference.
That's good stuff, I'm forwarding it to all my sites with backup generators. Already told them some time ago to only fill up with winter diesel as that is supposed to last longer, but now they need to test as well.
I took lots of video today in an attempt to describe the vibration sound I talked about at the beginning of this thread. Only one of them even came close. It's audible at the last second when the rpm's hit 3k, but it isn't nearly as distinguishable as it is in person. It only seems to do it in drive at 3k rpm's and when the truck is moving 40ish mph or above. In the video it doesn't do it until the third shift.
Here's another. From inside the cab, it sounds like a rattling heat shield. While replacing the fuel regulator I did find that the nut holding the dip stick tube to the valve cover screw was way loose. I'll find out tomorrow if it was that or low fuel pressure, or if the cause remains to be found.
I finally got around to dealing with the old fuel. I bought a Racor filter/separator that was recommended by their tech support; said he has one on his Duramax with no problems. I'm going to use it on the bench as a prefilter for the HFCM. (Thanks for the suggestion, Jack)
I don't have an extra battery laying around. I was thinking about getting a transformer to power the pump in the HFCM. The fuel pump fuse in the truck is 20amp. Does it necessarily stand to reason that I'll need a 20amp transformer too? I guess it would be useful to know the actual amperage or wattage the fuel pump requires.
Using SAE's factor for fusing, it probably draws 15 amps pushing against the ~60psi of the system. Since you are not pressurizing, you may be down to 7-8 amps.
You much have a lot of fuel to invest in that filter!

I measured 0.2amps at idle with my Fluke T5-600. That does seem rather low but I don't have another meter with the "amp clamp" option.

Maybe...maybe not. When I'm done cycling the stored stuff, I'm gonna put it on the truck and cycle the fuel on 6-month intervals if not more often. I could have spent a lot less with a lower flow rate but I was afraid of going too small and figured the bigger one would last longer. It comes with a filter minder, so that's nice.
Ain’t none. I just need to bolt it together. Short block’s done, heads done, turbo done, just about everything is painted, just not a high motivation project right now.

I'm going to measure that.
