Anyone know the legality of the fuel tank issue.......

Seeing as they are made of polywhatsit or steel, both not exactly bulletproof. I have researched the following and need to know if its kosher...
As I have LPG tank under the chequer plate rear tub I don't need a full YJ tank hanging underneath... (this is all to do with the rear winch mount scenario from a post last week)
Now,.... I spotted on a welding forum, that I am on, a bloke that made a tank from a Gas bottle.... In my case a 4.5kgs bottle would give me the height for the YJ and sender, obviously gas out and safety are paramount but after bottle is empty and filled with water and then top cut with hole saw they do make an extremely strong ready made fuel cell. (the bloke in question was building an off road  only buggy) Anyone know the legality of all this, MOT  I'm thinking?

Also spotted this piece of info on Pirate... To work on gas tanks (petrol) empty tank (obvious) and then fill with dry ice the ice will evaporate as it heats and take all petrol fumes out with it.... Industry practice some where Stateside apparently.

Have you asked you welding instructor about your intentions

Found this link when we put Clayts fuel tank in the back of his truck. To me there doesnt seem to be any standard/certification stamp on the Fuel cell?

Part 6.7 of the MOT check (scroll to bottom of page)

a gas bottle should be more than suitable for a petrol tank and the wall thickness is probably double the thinkness of a conventional tank. As for cutting and welding there shouldn't be a problem as it hasn't been soaked in fuel so the explosion risk is negligable. getting a good weld seal will probably be the trickiest part.
 don't think the mot tester will fail on the fuel system as long as the filler is sealed and there are no leaks.

most fuel tanks are pressure tested to failure to check integrity, this pressure can go as high as 45bar+ on a conventional tank (method is using water under pressure which is safer).

Thanks guys ....as I thought ... Just better paint it a different colour! 
No, haven't mentioned it to the welding teacher...yet    Having a go with the plasma cutter next Mon! Got two test peices passed for the C&G certificate! Like being back at school except this time with some purpose! Welder arrives next week or so so need some scrap to get dialed in.

Could swing by to give a hand and pick up some off cuts this Sunday, (it's either that or another trial thing of going thro canes with a bunch of the Green Oval persuasion)
