For well over a year my 2015 RX has been driven very little and the gas is likely stale. I’ve found where I can jumper the fuel pump relay so I can turn on the fuel pump to pump it out. My problem is that I don’t know where I can easily get to a fuel line under the hood where there is a quick disconnect. I’d like to connect a hose to a quick disconnect on the fuel line to pump it out. Is there a quick disconnect that is easy to get to?

How much gas is in the tank? If you have a quarter tank or less, I would just fill it up with fresh gas and drive it.

Almost full. I plan on putting small amounts I remove into other cars.

If tank was almost full, less chance of evaporation and absorbing moisture, just run it first to see if it runs rough or stumbles.

After using a 1/4 tank, top up with premium, and repeat.

Not sure if these tanks are siphon proof, but get a siphon pump and a length of 1/4” tubing and try the old siphoning way to remove some.

At idle it runs smooth and doesn’t stumble but I know some of the gas may be well over 2 years old. (Belonged to 104 yr old relative who passed away so it wasn’t driven). I didn’t want to do damage to the car if it had gelled. Will try the 1/4” hose, but would be nice to know if/where I can attach a hose to the fuel line, —if anyone knows.

The gas line has quick disconnects just above and behind trans, you will need to remove the air box, and maybe the battery box to get at it, possibly the MAF too. All those things were off when I disconnected mine for other reasons. I would just run it, at most add some fuel dewater stuff, cheap and makes water go into solution, likely will disove "goo" too, check out fuel stabilizers, a bottle of that won't hurt anything either.

I agree, just add some gas treatment and fresh gas and keep topping it up.
Or buy a cheap siphon at an auto parts store and a couple of 5 gallon cans to pull gas from the fill hole. It is too much trouble to do it the other way.

After removing a few things, I found (segments of) the fuel line after looking at the picture above and crawling around a lot. Since the car is like new, I agree that significant disassembly isn't worth it for me especially since it seems to run OK on the gas in it, and because I now know that running it until I can get it diluted won't damage anything. I did try a siphon pump I had with a 4-foot hose. The hose went all the way in and a section was covered with a little gas but (for whatever reason) it was never submerged. I also blew into the hose to confirm this.

I put a $6 bottle of STA-BIL storage in the tank and also bought a bottle of the $2 de-water stuff. I'll follow up with injector cleaner on the next tank-full. Thanks everyone, all of this great advice has been extremely helpful.
