Flush gas tank.

[PhredValk]

Hey. I will be removing my gas tank this weekend. I want to keep it in the basement to do some petcock modification, and don't want to smell up the house with gasoline fumes. After emptying it what should I flush it with? Water could be bad, so I'm thinking rubbing alcohol...
Suggestions?
Fred.

I would not suggest to flush it with anything.

Empty the tank as best possible

turn it upside down with the fill hole at the lowest point

and let it sit in the sun for a few hours.

Phred, have you tried to look around in there to see if there are problems such as rust? An inspection mirror will let you get a better look. If no rust or sediment problems, I agree with just let it dry.

It should be warm enough tomorrow, I'll give it a try. Thanx.

It depends on how long you want to let it sit around smelling.

I used engine fogging spray for the IS tank when I shipped it. To prohibit rust and cover/remove the smell of gasoline for shipping.

You can take a hose from the tailpipe of your car running and stick it into the tank. It will dry the tank, and the fumes will get rid of the gas fumes. I don't know the science, but, it works for the guys welding on the tanks

Flush tank out on nice white (wife's) towel, and you will see any red-ish stains or tiny rust particles, and give you a hint of what's going on in the tank.

There's vent passages in there. There's not a right way to turn it
(that I found) where all the gas comes out.
