Vacuum pumps are used on A/C all the time to remove moisture. I had a taillight on a modern car that was sealed, the seal broke and got moisture inside. I taped a vacuum hose to it and ran the vacuum for about 3 hours and it was dry inside. Resealed it and has been dry since. I can't recommend doing this on your fuel tank but if you did, I'd be very careful about how much vacuum to use. You don't want to collapse the tank.

Hardware/Plumbing Stores have a NEEDLE type valve, that fits perfectly in place of the original valve! ONLY about $4.99. I've used them.

I have not be able to remove the fuel shut off valve. The leaf blower pushed out all the standing water.

I had moisture get into modern "sealed" headlights, drilled a 1/8" hole in the lowest point in the lights so they could breathe, no more problem.

I first washed out the tank with oil eater. This removed the goop from old gas. Then I tried alcohol in the little water in the bottom. That mixed with the left over water and flushed out much of the trapped water. Per your suggestion, I added a couple of cups full of acetone and waited about 3 hours. I drained that out and there was color to the mixture, meaning the acetone was working on the rust and what ever was left in the tank. I removed the drained liquid from the garage. Tomorrow I will see if the tank is dry inside. If so, I plan to pour a bit of Evaporust in the tank and drain it out to be sure all the water is gone. Then fill the tank with Evaporust and let it sit awhile.

I'm going to drain out the Evaporustte this morning and I hope the rust is gone.

Evaporust drained out and saved. The first 3 jugs of it were very dark. thereafter it lightened. up I shook the car the best I could. I guess I should have tired to stir the mix with a paint stick. Tank fully rinsed and now drying. I don’t know it it has to be fully dried. Then sometime refill with Evaporust and drain out again

With cooler temperatures I have found that longer soak time is needed. 80-90* 24 hours would be fine. I wouldn't have worried about some water in the tank as Evaporust when it evaporates you add water to it.
