Joseph; if you park in a heated garage in the winter with a partially filled tank, the moist air that gets into the tank causes condensation. Enough cycles of this and you have enough water to foul up the fuel system. If you do not fill the tank For the last 30 years I have been putting “gasline antifreeze” in my tank to avoid this problem, as well as keeping the tank relatively full.
Here Walmart sells it in small bottles called Super Tech gasline antifreeze, and it’s likely isopropyl alcohol, which absorbs water.
