I try to fill it up with it needs At Least 30 gallons,
with the Fuel Sump installed now, I could draw it down to about 40 gallons with 4 gallon reserve, but that is too tight for me.

so 35 gallons at 15+ mpg on average is far enough for most of my trips.
that's 525 miles, surely I can find a low price refill before then?

in this pix of Fuelio, an Android app, the top fillup is actually a Refill of the fuel that we drained out of the tank, and pumped back in.... we lost some, due to having to pump some excess into my son's RAM Cummins fuel tank... our barrel was too small for what was still in the tank when we installed the fuel sump.

My first thought was, "Damn! That's a great price." Then I realized you got 49 gallons into a 48 gallon tank. You win!

Yeah I was sweating it, my truck decided to regen at 40% on the Kilpatrick turnpike north of Oklahoma city, auto regen is now shut off. I drafted a semi for probably 20 miles at 60 mph. My dte went to zero about 10 miles from the gas station.

Woah! That's a little scary. I agree that running out of fuel is a really, really bad thing on the PSD so I get very antsy when my F350 SB gets to empty on the gauge. It has a 35ish gal tank and I've never put more than 32 in at a fill-up though. I use Stanadyne to help keep water in the separator where it belongs.

One reason said for not going beyond a half tank is due to condensation build up from the replacement air. Get some damp air in there, park it overnight on a dewy night and it could condense.
I usually fill at half tank because thats where it lands after 3 days of driving to work and I fill on the way home on the last day. While traveling I get to 1/4 tank and look for a station.

You bring up a good point. What I came across from looking into ULSD fuel was that the very process of hydrotreating fuel to make it ULS, it makes the fuel more able to absorb moisture. Being in a cold winter state like mine, after shutting down the truck in winter, the fuel is warm and the air temps are cold. Good recipe for that to create moisture in the fuel as the fuel cools down, just like engine oil and how my catch can collects water in the winter time. From the oil cooling down and moisture forming in the oil when it does.
