07/14/10The gas tank had some issues. There was a nice sized dent in the top of it and the inside was quite rusty. There was still about a cup worth of ancient gas in it as well. The petcock also had its straws completely eaten away by that cup worth of gas which means I will be buying a whole new petcock.
So, to fix the rust problem I bought a few gallons of distilled white vinegar and filled the tank to capacity. I first had to plug all holes in the tank ( petcock back in and the tube that connects the two sides of the tank back on). I let that soak in for about a day while giving it a shake every once and a while. I then dumped it out, rinsed it out with a garden hose and repeated this process. I'm on the third round of it right now and the tank is pretty much down to clean bare metal. Using vinegar is a nice cheap and safe alternative to expensive toxic metal strippers.
To remedy the dent issue I found a fitting that screwed right on to the petcock hole in the bottom of the tank and connected that directly to the garden hose. I then closed up all holes and the cap and turned it on. The pressure built up enough to pop the dent right out. There is now no evidence that it was ever dented. Yippee!
