Be sure not to reuse the old oil that will be dumped out of the tank, since it will most likely be contaminated with gas. If you want to run the motor as is for the time being, I would go ahead and mix the gas 50/1 just in case. It may smoke a little more at idle, but at least you will be protected. After you install the new tank and oil check valve, refill with fresh oil, and your’e good to go. The oil pump drive gear on those inline models are extremely dependable, so I wouldn’t worry to much about that. Sounds like you have it covered!
