I impulse bought an orange gas tank online. One of my many regrets in impulse buying my bike was that I wanted a brighter color lol. I really wanted the bright red, but only found dented ones for a reasonable price. Found this orange one instead and mashed the buy button lol.

Some follow up questions:

1. How do I get last bit of fuel out from the old tank? There is still quite a bit swishing around even after I took off the fuel cap and fuel pump and poured gas directly from the openings. At the moment, it is just turned upside down in a pan hoping the remainder will eventually dry out/evaporate.
   

2. How can I help prevent the old tank from rusting in storage? I'm not necessarily planning to use it again, but just in case.

3. How the fuck do I get fuel to pour out of this gas can with a "safety spout"? Basically you push on the spout to get it to pour, but it only barely dribbles out that way. The red tab I think needs to be depressed or moved somehow but it won't budge. Any ideas? I just ended up removing the spout and pouring it directly out of the can via funnel

Bonus: Looking for some ideas to temporarily decorate the bike for Halloween! The bike is kept outside tho so it would need to be somewhat weather proof lol.

My brain saw this and jumped straight to KTM lol

To prevent the empty tank from rusting, you can use fogging oil. It should be available at your nearest auto part store. It's the same stuff you spray down into cylinder bores to keep them from rusting in storage. You'll also want to cover the giant hole where the fuel pump goes. For tanks on carbed bikes rather than fuel injected this is rather easier, because all you have to do is put the cap back on and close the petcock.

The redneck method, especially for tanks with petcocks, is to just leave a pint or so of kerosene in it and cap it off. Obviously, drain most of it out before you use the tank again, or at least enough of it that once you dilute it with gasoline it won't matter anymore.

I should add, if there's already rust inside, derust before applying the oil or it will continue to get worse, though at a slower rate.
