Every screw up is an opportunity not to make another one.

Just track your fuel used in the DIC (if you have one)
It's accurate enough to trust somewhat
I've been doing this for 2 yrs now.
I've heard dropping the tank can be a real pain, so I
am in no rush to change the sending unit.

Just a FYI, try to avoid driving with a tank below 1/4 as the fuel also serves as a way of cooling the fuel pump/sending unit. If the pump gets too hot, that leads to premature fuel pump failure. Something I learned about 8 or so years back when everyone on here had GMT-800s and had the same issues

my 01 with gasser had same problem, except my fuel guage would bounce all over the place......i changed just the sending unit on mine, which included cutting the main harness and put on an updated plug on since it for some reason was changed...
My GMT-400 Gen1 Vortec is having a bit of a stumbling issue that could either be the injection spider or fuel pump (I'm getting a fuel guage today to potentially eliminate the pump as part of the problem). Anyway, while researching I noticed that most 3rd party replacement fuel pumps contain a new wiring harness. Apperently the original GM harness has too small of wires which helped with over-heating when the pump was drawing full amps. The redeisgned harness was designed to handle the load better and give you more fuel pump life. I wonder if your '01 pump was similar.
The question I have, relating to the original topic:
Is it easier to drop the tank, or slide/lift the bed?

Thanks for the advice. I don't have a DIC on my '01 but I've been going off of mileage so I'll keep doing that for a little while till I have the chance to replace the sending unit. I was told that the pumps for the Duramax's were different and that the sending unit could be replaced without replacing the whole pump assembly. Is this true?
i have been going off of trip since 2004 on my 2001
