I try not to keep alcohol in the house because I can sometimes drink more than I should. Not that I get drunk but I don’t need the calories. Saving money is another reason. But I’m using alcohol to calm my nerves right now. I do better to make it an event. Knowing I have to drive somewhere to get the beer and drink it there and drive home. I’m less inclined to drink too much.
Moisture in the air gets into the tank over time. My guess is the ethanol in gasoline that attracts moisture from the air. Older cars suffer from it more. It’s fuel injected btw.
It seems odd. I've never had the problem myself, at any temperature in any vehicle. My vehicles are in their mid-20s, fuel injected. How often do you drive the vehicle? Fuel pump humming with key on/engine off? This is a very uncommon issue.
