Given the debate over the benefits of storing your rig with a full fuel tank of gas or one nearly empty, I should mention that it is "NOT" a good idea for most vehicles these days to run your fuel tank below 1/4 full. The reason is that the electric fuel pump is located inside the fuel tank standing upright in most cases, attached to the fuel gauge sending unit. 1/4 full keeps the fuel pump at least partially submerged in fuel which keeps it running cooler. The life of your fuel pump will greatly extend if always running cooler. Fuel pumps are expensive to replace. Never let your fuel go below 1/4 full and your fuel pump may never let you down.
That was a tip given to me from a very good auto mechanic.
A quick search on fuel pumps and I found this motor home applicable example, shown with accommodations for a generator fuel-tap. The fuel pump is the silver cylinder at the bottom.
