Default Removing Old Gas

So my car is a total garage queen that gets rarely driven. Last year I probably drove it less than a handful of times (probably used 1/10 of the gas) and topped it off with fresh fuel before storing it in the fall. The year before that, I added Stabil before it got stored for the winter.

I’m assuming that the gas has lost a lot of its quality and I want to remove the old gas and fill the tank with fresh fuel.

Has anyone been successful in siphoning gas from the filler neck or do our cars have that ping pong ball block which prevents that? For those who’ve removed gas from our cars, how’d you do it?

Thanks forum bros.

Never tried it, but I would think you could disconnect the fuel feed line at the filter and then let the system try to prime/pressurize to pump the old fuel into a container. No idea how long it'll attempt this before it shuts off but I would imagine it would take a good while to get 12-14 gallons of gas out of there.

For what it's worth, I'm pretty sure I've run lawn mower gas around this age that had stabil without much issue.

Thanks for your reply. I was thinking of maybe using some sort of vacuum to help with that process. The only problem is that wouldn’t that distribute the bad gas across the fuel system?

Funny, I was planning on giving away the gas to my family and neighbors to use with their lawn equipment.

I've never used it but you could likely rig something similar with flex PVC from home Depot and a T fitting and a vacuum source.

Gasoline is blended differently for different states... I don't know how Chicago gas compares to CA gas.
Out here... it seems that gasoline lasts a LOT longer than it used to. Used to start smelling like turpentine in about a year, and no good at that point.
My Wife has fuel in her boat from at least 4 years ago. We start it every couple of months... always fires immediately once the fuel hits the carb. I'm amazed, but it still smells fresh!
If your gas still smells like gasoline, and not turpentine... I'd just burn through it. I wouldn't take it to the track until it's gone through a tank full, but I wouldn't hesitate to just use it up.
