Joeman Posted July 17, 2014 Share Posted July 17, 2014 Empty it out, leave it to vent for a while until all the vapours have gone before you do anything.I'd be tempted to chuck a match in their too to prove the point. Dont put water inside, you could cause it to corrode. Quote Link to comment Share on other sites More sharing options...
mattycoops43 Posted July 18, 2014 Share Posted July 18, 2014 The metal will not stop giving off fumes, unless you leave it for months to vent off it will still go bang, especially if it's rusty, the rusty bits will hold crap and petrol.Water is one way, it will be fine as long as it's properly dried out afterwards, but another alternative to that is fill it with sand, it replaces all the gas, so while the petrol might flame, it wont go bang.Haven't done it yet, but have seen it done, and am about to try it on an RD tank. We're doing the sand route. Quote Link to comment Share on other sites More sharing options...
Joeman Posted July 18, 2014 Share Posted July 18, 2014 there wont be that much left. a lit match at arms lenght would confirm... worst case you get a "poooooof" and some flames shoot out - it certainly wont explode! Quote Link to comment Share on other sites More sharing options...
Mr Fro Posted July 18, 2014 Share Posted July 18, 2014 I did the water thing when I made a couple of wood burning stoves out of old gas bottles.They didn't explode. Quote Link to comment Share on other sites More sharing options...
Tango Posted July 18, 2014 Share Posted July 18, 2014 I had to drain and wash the tank of my old Speed 4 when it needed a new pump plate stud welded on. Washed the tank with water over several days......welder wouldn't touch it if it had even the slightest smell of petrol.... Quote Link to comment Share on other sites More sharing options...
Guest Posted July 18, 2014 Share Posted July 18, 2014 Run a hosepipe from a running car exhaust into the empty tank, that will purge the fumes Quote Link to comment Share on other sites More sharing options...

Chrissb6 Posted July 20, 2014 Share Posted July 20, 2014 Hi, If it going to be tig welded you could purge the tank with Argon gas Quote Link to comment Share on other sites More sharing options...
