[TheForge] OT question on diesel storage

[Dan Scheid]

I'm in the process of moving and rebuilding the horse ranch. The new
property has no power. In 4 month the seller is bringing in then power. So
until then we are on a generator. . After power is brought in we are going
to keep the generator as a back. Up. Here's the rub the tank for it is 250
Gal. my worry is water or it going fowl over months of sitting. I was
thinking of getting a sealed cap on the tank to keep the water out. But does
Diesel go off like Gas? Ideas?
