I’m not convinced you do. What do you think replaces the fuel in your tractor-tank as it is consumed?
It is true that storage tanks also suffer the same fate.
(The most memorable event of this problem came to my attention circa 1980 when it was required to replace the lower wing-skins of a jet that had not been regularly treated with biocide. The little varmits ate the fuel and pooped in the water at the bottom of the wing-tanks which corroded the lower wing skins …(which make up the tank)….. until after .010” had been etched-away in less than ten years of service…which weakened that load-bearing surface. The invoice for that was more than a lifetimes salary for most. )
Again....my assumption is that we are generally talking about STORAGE of diesel. Maybe there is a communication problem?
As I referred to in post #15, STORING a vehicle with a full tank minimizes the infiltration of air.
Prior to that (post 7) I said to KEEP the fuel dry by using a demulsifier. A emulsifier does not separate the water for removal. Hence, does not allow it to be removed. It's also not recommended for CRD, so I keep it simple with all my diesels and use one additive for all.
If the moisture is continually removed through an additive then the chance of it being in a FULL tank of STORED fuel is negligible. There is no consumption of fuel, so no air is introduced. Pretty simple. If one wanted to go all silly they could just fashion a dip tube and suck out the bottom of their fuel tank every so often while the vehicle is sitting.
Aircraft fuel may be different. I dunno anything about that (except we used to get 100LL from the regional airport for our race bikes). What I do know is diesels for land and sea. I was only 2 weeks old on my first ocean excursion and lived at a marina for 16 years thereafter. Which, BTW, is where we did use dip tubes for both storage and craft tanks. Bit that's the nature of the marine environment.
