I don't know anything about a V92 but I have been through a similar experience with a vehicle.
Some years ago I had a bike an EFI HD that I parked for a few years.
I put a double dose of stabilizer in each year that the bike sat. But didn't pump out the fuel.
I think mine went 3 years or close to that.
When I went to use the bike I used a little hand pump from Harbor freight :
to pump out as much fuel as I could. and because it smelled good, was not discolored, and was clear, with no sediment in it, I threw it in the tank of a fuel injected light truck that I had.
Were talking 2 gallons in with 15 gallons, The trucks tank was 3/4 fuel when I did this. My thoughts were that it would dilute and burn and I wouldn't have to figure out how to dispose of it.
Doesn't work that way. Took the truck to another town an hour away, got about 6 mile from that town on the highway and suddenly the truck lost all power. I pulled to the shoulder and kept it running on 2 then 3 then 4 cylinders for several minutes on the shoulder. Eventually it had some power and I limped it to the Napa in that town where we kept it running and added a can of seafoam and a can of EFI cleaner to the tank. After driving it around for a while in town it finally got to the point where it seemed safe to shut it off and we got more fresh gas and all eventually was good.
The problem isn't necessarily sediment. It's that under storage the lighter more flammable components of the gas evaporate out. What is left behind does not burn under spark ignition.
Because of that experience I would buy the pump above and try to get as much of that old fuel mix as I can out of the tank or just pull it and dump it like you said.
But there I would stop and put fresh gas and seafoam in it and see if it will run before you proceed any further.
I would stick with seafoam because as per the instructions on the can you can run a motor on it straight without damaging it.
If it works and it starts and runs at some point shut it off with that extra strong dose of seafoam mix in it and allow it to set for several hours so the seafoam can get stuff softened up.
I'd continue to add some seafoam for a few tanks after it gets cleared up then stop. Over cleaning injectors isn't good for them either. But over cleaning will be down the road from where you are now.
