Winter hibernation Options

[Grosbard]

I was thinking a bit about winter car hibernation. Of course one issue we face is the ethanol-laced fuel attracting water, so adding sta-bil to the gas tank is a must do. But I'm wondering if there is more we can do.

I am guessing that the prime locations for water to enter the fuel system are:

1. the gas cap (which looks to be just a metal-on-metal seal and thus probably doesn't seal as well as a modern gas cap)

2. the carburetor air intakes.


If that is true, can't we improve upon things for winter storage by just wrapping both areas in kitchen plastic (Saran) wrap or something similar? Or is the system so full of areas where air can enter that this is not moving the needle in any substantive way?

Thanks in advance!

I only use pure gas with some Sta-bil, full tank for storage. Even then it's only good for no more than 6 months.

If I could only get gas with ethanol I'd drain the entire system.
Ethanol gas (E10) starts to smell like it's going bad in as little as 2-4 weeks.

I don't like the idea of plastic on the tank cap, etc., for one it could melt if incompatible and the other is you might forget about it, suck it into the tank, carbs, etc., and cause a world of problems.
I had a customer put bounce dryer sheets in his car and engine bay to keep the mice away, next spring forgot about them, sucked them into the fan and it cost him his engine.
