My Street Demon install experience

Your insane for replacing that tank. There’s absolutely, nothing wrong with it. It’s in incredible condition. All you have to do is buy a couple gallons of Evaporust. Slosh it around in there for a couple days. The rust will be gone. If you feel very frisky. Seal it with a $20 can of Por-15 tank sealer. Add 2 filters. I’m all for replacing a tank when it needs to be. But, that’s a total waste of money considering it’s condition.

Not insane. Add in at least half a day of screwing around dealing with chemicals and you're well on the way to a new tank. Some things just aren't worth messing with unless you absolutely have to. I'm all for saving parts, but this is an easy decision.
