Auxiliary Tank Concern?
I’m considering adding an auxiliary tank for camping season. I looked at the Titan 50 gallon replacement tank but can’t justify the cost. The 30 gallon ATI auxiliary tank is perfect for my needs but I’m worried about condensation during the times that the truck sits. I have a work vehicle so my truck will sits for weeks at a time in the winter, it’s mostly used for towing the fifth wheel in the summer & I don’t want to deal with the tiny gas stations in New England while towing.
My plan is a simple gravity fed system with an electric solenoid but I’m seeing that most if not all aluminum auxiliary tanks still leave a gallon or two of fuel in the bottom due to the placement of the fuel feed. Short of removing the tank in the winter to avoid condensation is there anything else that I can do or am I overthinking this whole process?

That’s what I do with my tank currently but worried that it might take me a few months to use the fuel in the auxiliary tank. Not sure even with an additive how long the fuel will last?

If you use additives in the fuel, you only need to add to the main tank and not both tanks, main and aux.
on edit forget what i wrote.

Keep the tanks full, use a high quality additive, if you're really that worried about it, throw some biocide in the tank during the storage months (winter is not ideal for microbial growth, water is a different story) Service your filters regularly and just be happy and motor on. In the right conditions diesel fuel will last a very long time. Before I moved my 2014 rarely got used, kept the tank full and have always used a high quality additive, never any water contamination or fuel related problem to date.

The old 7.3 would run on kerosene......well, almost...it is not as particular about fuel as the common rail setups now days...

That’s my concern, these 6.7’s are rock solid except for fuel issues so adding some risk with old fuel has me concerned. I always use an additive with every fill-up, never going below a 1/4 tank & always parked with a full tank in the winter. I recently switched to Opti-Lube & will use their winter blend when the time comes.

actually kerosene is an approved fuel for the 7.3, I put over 50,000 miles on one running kerosene.

I had an old 7.3 IDI that I ran on Waste Vegetable Oil for a number of years. Sometimes I miss the clankety sound, the smell, and the simplicity of that truck.

I installed my new S&B tank last weekend. No issues, it went in perfectly, and I’m happy to see around 1000 miles DTE. Like another poster stated, the worst part was taking off and putting back on the filler hoses. Those things were a bear!

For what it is worth.
I installed a 52 gallon Titan in my 2006 GMC short bed. Under 2 hours, fairly easy and in my driveway.
When I listed the truck for sale I had multiple people contact me about the tank (I had listed it with and without upgrades). I had offers up to $600. I had disposed of the original so the new owner got the big tank.
Never any issues.
I installed the 65 gallon Titan in my 2011 F-350. Under 2 hours, fairly easy and in my driveway. This time I cleaned out the tank and stored it in my basement. Then we moved last year and I trashed it.
Last August when I listed that truck for sale I found a totally failed tank strap - rusted completed through. Called Titan and they wanted $300+ for new straps. Seems my tank was purchased just before a lifetime warranty was in place. A bit of finagling and Titan sent me the straps no charge.
Not doing an in frame tank at this time, but if I was it would most likely be a Titan.
