I also want the extra fuel tank to run the fuel through a water separator my truck only has one fuel filter on it I think this will help

In post 15 I put in the URL for the tank I have, it comes with a fuel filter that they recommend changing once a year.

They only thing I can think of is if you use a steel tank instead of aluminum as it could rust over the years and that could add debris to the main tank. But otherwise, I think you are overthinking the fuel issues with an aux tank gravity feeding to the main. As for cost, I saw it this way. I was going to buy a in bed toolbox, a good aluminum one cost around 300-400 bucks, I paid 695 for the tank/toolbox combo. At 45 gallons in just my vacation trip it will save me around 30 bucks for just that one trip. When I went to visit my mother in NY, it saved me another 15 bucks over the cost of diesel on LI. So the more I avoid more expensive states to fill in, the more I save over time.
I'm not judging, just say 'n. When I pump from the aux tank, pumps through a water/particulate filter . if the aux tank is not kept with some fuel in it, it is then ,like the factory tank, subject to condensation. Two tanks=twice the potential for some water. If possible an in line filter ,between them might not be a bad idea.
I like the idea,of gravity feed. When I installed tank,and got to the wiring, I got lazy ,and just clamped cable clips, like battery charger size, to the 20' pump cord. When using for farm,I carry an extra battery in a storage box,in bed. The battery is also used for bulk tanks, to equipment pump.

40gal transfer tank here.....I take it out when not hauling has its own water/part filter before I pump into main tank...

I will say that full of fuel and fully loaded 318bhs (9000-9200lbs) the truck is pretty much maxed on payload..i upgraded to the 350 leafs/block and rear axle when I first got I KNOW its ok...but the scale numbers put me within 25lbs of maxing out my 10000lb gvwr!!

nothing else I tow comes close to hitting GVWR so I don't mind...texas is a big state....I don't like stopping every 200miles for diesel as in the smaller towns its expensive...I did it for years tho...just have to think ahead and plan your stops a lil more..

Yeah, I just dont see it as something needed if you gravity feed. My friend has a 100 gallon tank, uses it all the time and has never had an issue with the two stock filters and seperator doing the job. I think if you where to only use the tank for trips and keep the gravity fill turned off the rest of the time you run a higher risk of doubling the water, but otherwise, I dont see that as possible.

you sure are asking an awful lot of a couple 1 inch tied down straps. even if they are 2 inch straps, there is no way thats safe or legal.

My tank goes from one side of the truck to the other side and I have never given it any thought to the tank moving, it can't go past the wheel welds. As far as water goes I have never had a problem with water in the fuel filter, I have the chevy place change that. I have used my tank for over 5 years and I might have a problem tomorrow but I have not had one yet with tank moving around or water. My 12volt pump works just like a pump does at a station, I may put a filter on the handle later, I have long leads from the pump motor and when I need fuel I just open the hood on the chevy and hook the leads to my battery and turn pump on. Does not take long to fill up, works like a charm. I went to Yellowstone this year and I saved $125.00 on the credit card alone. $2500 dollars at 5% adds up plus all the places I saved at least .10 a gal on, plus all the time I save driving instead of at a gas station

thanks for being the police officer...that was only temporary, it never had fuel in it at that time, it is bolted down when installed.

I ran the fuel line into a inline filter before it went into the filler neck tube, and let my 4 other Fuel filters clean it better

I have an aux tank, gravity fed. My son and I installed it in about two hrs. The tank makes our trips much safer because there's less city driving - looking for a Diesel pump, less maneuvering with the 5er. When we stop for lunch at a roadside rest, or other safe area, I open the valve, leave it opened, watch my main tank fill while driving! The tank saves us time as well as money - no stop and go in town. I fill up after setting up camp, or I go out the morning we leave and fill 'me both.
