Method to Clean Gas Tank

[SteveW]

I have an old metal gas tank for Johnson motor and it has been sitting for awhile.<br /><br />What is a good method for cleaning it out and proper disposal of old gas?

Re: Method to Clean Gas Tank

i had an old metal tank that rusted and clogged up my fuel filter really bad. I could not understand why my Mariner 40 would cut out. When I got to checking the fuel line and such I found it. Tons of metal debris floating everywhere. If it where mine I would trash it and get a good plastic tank. This is my opinion for what it is worth. Oh yea, if you decide to keep the tank I think Advance Auto, or some place could use your old gas, if not put it in the mower and cut the grass! Rubbing Alchol will clean old gas out but I would be sure to check for debris floating in your gas. Those metal tanks have a plastic liner that will age and rot over time. Just a thought <br />Oshi

I'd also consider just buying a new plastic gas tank...<br /><br />However, if you're set on using your old metal tank...someone in here once suggested it was possible to clean the rust and crud out of a metal gas tank by this method:<br /><br />Empty tank of old gas.<br />Add a handful of brass nuts and a quart of clean solvent.<br />Shake can like crazy.<br />Drain dirty solvent & remove brass nuts.<br />Flush well with clean solvent.<br /><br />I've never tried it, but it sounds as though it might work...<br /><br />FYI<br /><br />Walt
