Larry,
How long should diesel last if the tank is topped up with no void for
condensation ?


Diesel lasts pretty well forever, it doesn't have nearly the volatiles
that gasoline has and it doesn't have alcohol in it to soak up water. I
have used ancient diesel without any problems and you can use it as fire
starter as well, or solvent, it's much safer stuff.

I had the same question last year since I have 500 gallons of diesel sitting
in a boat that has not been used for over a year. It's a good idea to add
some biocide (even a little water in the fuel will encourage critter growth)
but the fuel itself will last indefinitely. I have to check something
though .... I know gas fuel tanks on boats are vented, but I am not sure
about diesel tanks. I think they are .... which is another reason to add
some biocide from time to time.

They would have to be vented, because as you pull fuel out, unless it
were vented, you'd create a vacuum.
