I am writing this to share my experience in removing my old "covid" fuel from my backup XC90, 2004 2.5T which has been sitting a lot; also with an eye to using this method to get gas to run my generator in an emergency if I run out of propane. This is not a DIY, and I am not promoting this method, but just sharing my experience and method for removing fuel from the XC90.
I had tried the standard method of siphoning with no luck and also looked into the "GasTapper" method, using a stiffer 1/2" OD hose with a small flexible hose threaded through it. Unfortunately, this method also does not work on the XC90.
What worked for me was to purchase a Schrader Valve Extender Hose like for a dually tire to fit onto the Schrader Valve on the fuel rail, I think also there is a Schrader Valve by the fuel filter, but I did not try that location.
Anyway, I removed the valving from the male end of the extension and fitted a piece of fuel hose to the threaded end there with some RTV on the threads and a worm clamp to hold it.
Next, after bleeding the residual pressure from the Schrader Valve on the rail, I threaded the female end of the extender onto the rail Schrader valve.
Next, I used a fuel line clamp on the fuel hose drain line and clamped it closed in order to build starting pressure when the pump primes in Pos.2. Then checked for leaks.
Next, I started the XC90, then released the clamp from the fuel line drain and it began pumping fuel into my gas can. It flows at a decent rate at idle and doesn't seem to affect idle speed or engine smoothness, it ran as normal.
This method seems to work well, but I haven't ran it by VIDA yet, wondering if it will set a code for pressure. I'll look into that soon. There were a lot of options for the Schrader Valve Extender, keeping in mind that the angled, all metal ones could have an interference issue on my other XC, I opted for a rubber hose one, here: https://www.amazon.com/Bluecell-Flexibl ... 188&sr=8-3
Does anyone see a problem with this method in regards to overtaxing or over-running the fuel pump for an occasional 5 gallon-ish drain?
Thanks

It’s a substantial technical lift from the method an ice pick through the bottom of the gas tank and a chewing gum repair.
Additional benefits
Your ice doesn’t taste like gasoline
You get to keep your chewing gum
You can collect a given amount of gas, not just the whole tank.
